Were you able to verify that enabling those two as modules make it work?
I honestly do not know how to check from userspace. xrandr has a Content Protection flag that is responsible for enabling/indicating HDCP usage. It works but I cannot verify it to be HDCP v2.2 (v1.4 works without those configs). libhdcpsdk has a HDCPSetProtectionLevel but I do not have the time right now to write a test program.
The time for changes for bullseye is thight, so would like to hear a confirmation, the needed changed could be tested and confirmed to work.
