You can create an SRV record, but the target has to be unproxied, if you're not using Spectrum (which is an add-on).
SRV records are usually structured like _application._transport.domain, so for example for factorio, which uses UDP, it would be
_factorio._udp.example.com. See the screenshot for an example:
And the target domain,
target.domain.com in my example is the one that has to be unproxied "gray clouded" for UDP to work. Bear in mind that this exposes your origin ip.
