U3223QE, after turn on MST mode, not working

I turned on MST mode in dell U3223QE and my monitor is not working then. Problem that now in the menu i can't open MST for turn off it again. How can i turn off it? I think my thunderbolt port in the laptop (acer predator helious) is not supporting MST.

By the way. Why MST doesn't work with thunderbolt 4 usb-c ports? I have laptop Acer predator helious neo with 4070, I9, 32gb.
