Installing additional dependencies

I’m running HA OS on a RPI 3b. I’d like to use pyscript to control the hardware PWM using pigpio, but in order to do that I need to (AIUI) both install and run the pigpio daemon, presumably on the HA Core docker container + also install the pigpio python library. How do I go about doing this?


By not using the Home Assistant OS installation method. This is a locked down OS not meant to be messed with.
