Disable UART on M2 pcie on BBAI64

Hello,
This post is part of debugging the following post:

I would like to disable the UART on the M2 pcie port to see if the 88W9098 Wi-Fi/BT (PCIE/UART) can be run if the UART is disabled. How do I disable it? Maybe through dts overlay…

Thank you for your help!
