I have looked and could not find a list of what GPU's support HDR10 recording with Action! 4. I am currently using an AMD Radeon RX 560 and the only options that gives me are AMD AMF and AMD AMF HEVC, and I do not wanna use my CPU because the recordings are kinda choppy.

It is not certain which graphics cards support this feature. But I can tell you that NVIDIA series 10xx and newer support HDR encoding. Also Radeon RX 5700 has it for sure.
