CPU: AMD Ryzen 7 5800X3D 8-Core Processor [4.45GHz] (8C/16T)

Potential issues:
--screen-content is enabled by default for AV1 specifically. And yet, palette-mode and force-integer-mv are both disabled at the same time.
[I assume it should be disabled by default, same as for other encoders?]
--cdf-update is enabled by default and cannot be disabled due to lack of the flag (or boolean value)
[In AMF documentation disabled by default]
--cdf-frame-end-update is enabled by default and cannot be disabled due to the lack of flag (or boolean value)
[In AMF documentation disabled by default... Which is kinda funny, as value to enable it is called AMF_VIDEO_ENCODER_AV1_CDF_FRAME_END_UPDATE_MODE_ENABLE_DEFAULT, but it is NOT actual default]
Also, how do b-frames related options interact with AV1? Afaik, AV1 does not use I:P:B frame division. And based on quick testing, while VCEEnc parses your inputs and even warns you if --bframes>3, these options had no effect on output.
Now for other options. I recently noticed that AMF docs say that temporal layers are also available for HEVC. Is there reason why VCEEnc only applies them for AV1 only? Granted i don'tsee those parameters in TranscodeHW, so maybe they are related to something else?

Some parameters having defaults differing from AMF docs and missing options to toggle them?
