Setting PWM Output to 3.3V

i have a Nvidia Jetson AGX Orin Developer Kit. I am able to output a ~1.8V PWM signal via port 15 and 18. However i need one of these pins to output in 3.3V. How do i change it?
Best regards

Hi, it can not be changed. You may need to add an external level shift or choose other pin for PWM.
