Try the following cmdline options if you haven't already, to in effect blacklist
i915 kernel module and to enable Xe kernel module designed to take i915's place
for Gen12+ GPUs:
xe.force_probe='46a3' i915.force_probe='!46a3'
Whether those options exist in 6.1 kernel I do not know. When I boot Bookworm
using those options they only show up on the two kernel cmdline lines in dmesg.

It seems to me you probably need to go backport. I tried the "experimental"
equivalent
with i5-11400's Rocket Lake S GT1 (Gen12.1) in openSUSE Tumbleweed, resulting
in loss
of about 2/3 in graphics performance testing with glmark2.
