TLS 1.0 and TLS 1.1 support will be discontinued on September 24, 2020

[Brink]

Microsoft builds and supports a variety of software products for Linux systems and makes them available via package repositories on packages.microsoft.com. To support modern security standards, packages.microsoft.com will discontinue support for package downloads over Transport Layer Security (TLS) 1.0 and 1.1 protocols as of September 24, 2020. This means that any connection using these protocols will no longer work as expected, and no support will be provided. In order to continue to access packages from packages.microsoft.com after that date, organizations will need to enable TLS 1.2 (or a later version). Where possible, Microsoft recommends that organizations remove all TLS 1.0 and 1.1 dependencies in their environments and disable TLS 1.0/1.1 at the operating system level.

This is what I currently have selected in Internet Explorer 11.0.205
The left image is in Windows 7 and the right image is in Windows 10.

I went through the settings in Mozilla Firefox 80.0 and can't find any TLS settings.

I haven't yet tried using Microsoft Edge in either operating system.

Firefox lacks customization unlike something like Pale Moon with the Pale Moon Commander add-on.

At any rate, the pref can be set and changed, but I don't recommend it simply because some websites may still use the old TLS versions and I'm sure what Firefox has there by default has its purpose. Also, the security.tls.version.min pref will allow you to already enter a website that uses an old and outdated TLS version.

To see your TLS settings in Firefox type, about:config in the address bar, hit enter. Accept the warning and do in fact heed its advice.

Above in the search box in about:config search for TLS. The options you're looking for may be at the very bottom.

If you are a power user like I am and modify about:config, it would be wise to backup the Firefox profile or just the pref.js file in the profile folder. pref.js is where all of about:config settings are saved. It can be opened with Notepad ++ and I've used compare and contrast programs like Diffmerge to find out what prefs are different from an old pref.js file to the next. This is how I found an issue with a Pale Moon (Also available in Firefox and Chrome) extension called, I-dont-care-about-cookies and submitted my findings to the Dev who happily corrected the issue.

To find the pref.js file in a hurry use the program Everything.exe and search for it. If you have Thunderbird, portable Firefox, portable Thunderbird, or another Firefox derivative installed, more than one pref.js file will show up. So make sure you know how to deduce which version you're after.

Addendum:

With the Internet Options in the Windows control panel, I have had an error with a program installer for an add-on in Flight Simulator X. The paid-for add-on for FSX used a wrapper program to buy the product and get the serial number. Well, this wrapper program to install the add-on used an older version of TLS that wasn't enabled in the Internet Options under the Windows control panel. So once I enabled it I was then able to buy my add-on for FSX. Why they supported an older TLS version I don't know. That wrapper (which was old as ancient Rome) has now been replaced with something called, 'The Flight1 Agent.' Just another PITA if you ask me. And despite all this crap, add-ons from Flight1 often end up on file sharing websites, but us legit users have to suffer the consequences with convoluted rigamarole that can cause issues and irritation, and in my case, a possible fist through the monitor. LOL I mean, you just want to buy the damn thing! Not go through a bunch of crap!

PS: The encryption settings in Internet Options can be found at the bottom under the Advanced tab. Th9is is where Internet Explorer gets its settings as you have found.But it encompasses the whole of the computer as well. And I think TLS settings can be defined in Group Policy (only available in certain Windows versions). In Windows server IIS I'm sure that's the case. And I know for a fact this website runs in a Windows server. HEHE.
