So what about following the IETF mapping found in section 4.3?
https://datatracker.ietf.org/doc/html/rfc8325#section-4.3

Thanks for this tip.
I will update this patch to have the default DSCP to UP mapping as per
above link and map all unused DSCP to UP 0.

Is there any mechanism/API for network administrator to change this
default mapping in the network drivers?

I'm not aware of any (appart from manual update with tc), but I could
have missed something. It'd probably make sense to have such a
mechanism though.
