Is there any option in vvenc similar to AQ mode or AQ strength of x265?

I guess qpa have similar outcome for vvenc as aq mode.
But QPA only takes value of 1

What is aq mode?

adaptive quantization

Yeah, that's quite similar. Except QPA is optimized for XPSNR. So the most important difference there is, it also has temporal weighting to calculate the QP offsets. QPA also takes value 0.

Yeah, just an idea.. wouldn't it be great if it qpa takes strength values to make it more or less agressive.

[adamjw24]

Well, I honestly think our QPA is very good just as it is. The SW is open-source tho, can't be to hard too add some weighting to the QP offsets.
