TPM on my motherboard is forever disabled and I’m going down with the Windows 10 ship. Another couple years and Proton will be even better than it already is.
Considering it's bleeding edge, it's probably pretty frustrating to do atm, I'd wait a little bit longer for proper HDR support down the software stack
If that's just to stop W11 that's stupid. TPM chips are security related. Disabling them has some serious drawbacks.
Now there are discussion on if you'd even want a TPM chip or not, and if you choose not to use it for such reasons it may be a well thought out decision. Then you won't hear me complain. But to trow out security components just to prevent an update, without looking at the possible consequences, is stupid. There are better ways to prevent that anyways.
