CC boundary devices guys, since they already have this on Nitrogen6x,
but they placed the PHY tuning into the board file (which I think is
more correct).

See the attachment, I think this might be a stab on what you want to do.

Also, I don't think it's necessary to explicitly define new ad-hoc env
variables, actually I doubt there's any need for any env variables at all.

Best regards,
