You could try the following kernel paramater.
amdgpu.ppfeaturemask=0xfff73fff
0xfffd3fff means that everything is enabled except for PP_OVERDRIVE_MASK, PP_GFXOFF_MASK, and PP_STUTTER_MODE
It might be worth trying. If using grub make sure to run the grub update command after adding the kernel parameter to the command line in grub.
