I bought this: https://www.amazon.co.uk/Woieyeks-Emulat...YKM1T?th=1

unfortunately it has only 8-bit color depth and no hdr and only 4:2:0. I tried to flash the edid using the edid from my LG cx oled dumped from my lg CX. However, that did not work. Can I use cru to modifiy the EDID so I can get 3840x2160 RGB 10.-bit and 120hz? How do I do that?

Dummy plugs usually only support HDMI 2.0 TMDS up to 18 Gbps. You need a dummy plug that supports HDMI 2.1 fixed link rate (FRL) at 48 Gbps, but I don't know any that do. YCbCr 4:2:0 shouldn't matter for streaming since that only applies to the HDMI signal and not the actual content, but HDR requires 10 bpc, so you can only get HDR at 3840x2160 @ 60 Hz with YCbCr 4:2:0/4:2:2 when limited to HDMI 2.0 TMDS.
