RS485 on Pocket Beagle

I am using pocket beagle with debian 10.3th vserion. I just want to know is there is any dtbo file there to start rs485 in pocket beagle?

Like; BBB have “BB-UART4-RS485-00A0.dtbo”, dtbo for pocket beagle is there or not.

Requirements: I don’t want to take care of enable pin in code. i want any driver/overlay take cares of Enable pin according to communication btw Master & slave.

**Need to make changes in any dtbo? **
is DTBO available?
have to take care code only?
