Are there any negative impacts from enabling TPM 2.0? (self.techsupport)

I'm on windows 10.

I occasionally like to play valorant with friends and starting in the middle of this month it's going to require TPM 2.0 to be enabled. I currently can't easily enable it because I'm on legacy BIOS for a reason I can't remember (and when I switch to UEFI, it can't see my windows installation). I have a new SSD that I can format in hopefully the right way to enable UEFI in the BIOS, but before I dive into fixing this mess I have some questions about TPM 2.0.

If I enable TPM 2.0, can windows decide to update to windows 11 without my input?

Edit, I looked into this a bit and windows makes it very very easy to click to install windows 11. It's kind of disguised as a regular windows update notification :/

Are there any downsides to enabling TPM 2.0? Are there any exploits I should be worried about? Will some legally acquired software not run anymore?
Bonus question - why would Riot Vanguard (valorant's anti-cheat software) need TPM 2.0 to be enabled? Would it be a way for them to stop players from playing on a virtual machine? Or is it more so they can stop cheaters?

              It shouldn't but I wouldn't put it past Microsoft.  That said, all it does is notify me that Windows 11 is available and ready to download/install.  It is a button above the check for updates option.
AMD previously had some issues with TPM installed that caused stuttering on games.  That was on the AM4 platform and has since been resolved. Not aware of any other issues.
No idea, try asking in a community specific for that game.  Might get better answers for that.
