Trying to extend display to 2 LG Monitors, but only 1 HDMI output port

Howdy y'all, got a question that has sidelined an LG C2 I have because I wanted to run dual LG TVs on my PowerColor Red Devil 7900XTX. I soon discovered that I only had one HDMI port on the GPU, which hadn't been a problem for me until now. I tried to use a DP 1.4 to HDMI 2.1 cord, than an adapter of a different brand, but I couldn't use HDR along with running the monitors at 120Hz with VRR/Freesync (I suspect that the 32Gb/s data rate was too low where the HDMI 2.1 cables are rated for 48Gb/s). If I turned on HDR (or the Game Optimizer, which turns on HDR automatically), the TV would lose signal. Is there a way to extend my display to a C2 and a C3 at the same time with the GPU I have?
