MacBook Pro M4 Pro and 4K 120

I currently have a TS3+ dock and with a recent MacBook Pro upgrade, considering upgrading to TS4 dock since machine can support 4K 120Hz.

My question is aside from monitor supporting that refresh rate, can I use the DP 1.4 port on the dock with a compatible monitor to get that resolution and refresh? or do I need to use a DP to HDMI adapter since Apple states "one external display with up to 4K resolution at 144Hz over HDMI"?
