UART not working when changed the pins in overlay file

I am working on a module MS12SF1(nrf7002 + nrf5340) module. I am getting uart data from another device to this device through uart. Earlier when I configured uart to its by default pins which were P0.05 (rx) and P0.06 (tx) it was working but now I want to change the pins to P0.11 (tx) and P0.12 (rx), I added the updated configurations in the overlay file but its not helping.
For reference I am attaching the Datasheet of the module and my code.
