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?

Yeah that's because UEFI requries GPT partitioning, you can convert it by following this guide: https://www.windowscentral.com/how-convert-mbr-disk-gpt-move-bios-uefi-windows-10

Or like you said, a fresh install on a new SSD will work too (just enable UEFI beforehand).

oh my god I didn't know this was possible! I might try this then do a clone to my new SSD. I would have so many files to copy over and programs to reinstall, I'd like to avoid a clean installation if I can

I'd recommend cloning it and then following the guide on the new SSD, just in case something goes wrong then you still have a complete backup.

I didn't even think of that! I'll do that, thank you so much
