Altimeter NRA 15 + Pixhawk 4

Good afternoon
There is a desire to install an altimeter on Pixhawk 4
There is an altimeter NRA 15 from Nanoradar
It connects via UART
The question is how to enable it in the firmware through the parameter tree?
They sent instructions, but it is for firmware from Ardupilot
Help me, I’m not good at writing a driver.
