Change Polarity of Hardware Generated PWM

Hello,
I am trying to do BPSK modulation and need a way to invert the PWM signal but I can’t find anything in the Jetson-gpio library that will allow me to do so. Do I need to exploit the lower level libraries to achieve phase control/inversion of the PWM signal?

Any hints on how i can achieve polarity change?
Thank you!

It’s not supported to invert signal.

Thank you!
Can I get register level access to the PWM module? Is there a way to know when a PWM period as elapsed?

Thank you again.
