Hi 2036063251,

What’s your Jetpack version in use?

If you want PP.04 default Output/High, you could configure it to Drive 1 in pinmux spreadsheet.

Have you confirmed the generated dtsi moving to the correct directory and you modify the PINMUX_CONFIG and PMC_CONFIG in your board config?
You could check the full flash log to confirm if they have been used.
