HP ZBook Create G7 Thunderbolt to HDMI ?

[Serbay]

Hi guys,

I have a ZBook Create G7 with i7-10850h, 16GB and RTX 2070 Max-Q

I read somewhere that my Thunderbolt 3 Ports are despite their bandwidth limited to 4K60 output via
USB C to HDMI 2.1 Cables. Will that limit be lifted if I enforced my BIOS Settings to only use the 2070 Max-Q as I currently do?

Like can I actually use my 4K 120Hz 75 Inch TV as Display Output via Thunderbolt 3?

Or do I really need to chuck out like 40€ for a Mini Display Port 1.4 to HDMI 2.1 Cable ?
