Yeah, every time I update the UEFI it pops up a warning that the TPM will be cleared and I better have disabled Windows Bootlocker before I did this. The warning also goes away within a fraction of a second because the PC reboots which is not nearly enough time to read it, and I only know what it says because I've updated the UEFI enough times to be able to piece it together. Weird.

It might just be a warning to cover their asses; ie it doesn't actually clear the TPM but they don't want to be responsible for your un-unlockable drive in case it does. I don't actually use the TPM for measured boot or anything else so I haven't checked.

In any case, UEFI updates are relatively common right now (once every couple of months or so) because it's a relatively new mobo (AM5), and because AMD is about to release new CPUs that requires corresponding AGESA etc updates. It'll probably become less frequent in a few years.
