Hi Michael, Rolling your own dnsmasq.conf is a non-trivial matter and possibly would make the Network tab confusing if many things no longer worked.
Over all the years, I don't recall having particular DHCP options set on a "data" LAN subnet has ever proven to be an issue. As Christopher reported, even if a device (Intel NUC) had PXE booting ahead of Disk booting it should still work, of course having Disk ahead of PXE would be best. Regardless what the DHCP response contains, it is up to the client configuration what it does with them.
