Hello @t2865k5 

I hope you are doing well.

Q)https://community.nxp.com/t5/i-MX-Processors/How-to-set-GPIO1-IO09-to-out-high-in-imx8mp-vek-dts/td-...

This is not recommended to use a pin that is already configured as an interrupt for touch screen events.
Because DSI_TS_nINT is the connection that is made with the GPIO_IO09 where gpio works as an interrupt for the touch screen panel connected to MIPI_DSI.

One can also check the pin connection made in the schematic for reference.

I hope this information helps you!
