@J-3804,Thanks for posting in Q&A.
Based on my research, the printer settings under device restriction configurations does not support network shared printing.
However, I find that we can create a Universal Print policy under settings catalog in Intune to configure the network shared printer.
Here is a link with detailed information you can refer.

Hope above information can be helpful.
