Probably the simple way is Mode:DV, Submode:DMR, (DXKeeper already maps
MODE:DMR to MODE:DV/SUBMODE:DMR) and Prop_mode:Internet or, if you know
the other station is on the same node (local repeater), Prop_mode:RPT.
In either case, the Prop_mode disqualifies the QSO for most awards.

DMR - Digital Mobile Radio. Commercial protocol that is licensed
fairly widely by ETSI (not Etsy - links:
https://www.dmrassociation.org/dmr-standards.html). DVSI's AMBE+2
CODEC, 4FSK, and TDMA over RF. Not an amateur protocol, so station
callsigns are not embedded in the protocol the way they are with
D-STAR and YSF. There is a registry of Radio IDs that maps them to
your callsign. Group call IDs are used as "talk groups". Most
systems are at 70 cm, but DMR could go anywhere a repeater could go.
Users have to put a file on their radio that contains these RID
mappings as well as (usually) name to "talk group" mappings, not to
mention individual repeater parameters (freq, Color Code). The local
folks have the config set that the talkgroups are changed by the
channel control and you move from repeater to repeater using the Zone
control (https://w5nor.org/okdmr/)

From a ham point of view, the best part is that 2-slot TDMA. For the

cost of one repeater -- which, in the case of the MOTOTRBO units,
looks suspiciously like a 1U rack-mount server with a Type N connector
on the back -- a duplexer/feedline/antenna, you essentially get two
repeaters.
I imagine that there are a few stand-alone DMR repeaters out there but
probably not many as most are networked over the commodity internet.
Brandmeister is (https://brandmeister.network/) is one network,
DMR-MARC (http://www.dmr-marc.net/) and yes, the two of them snipe at
one another. I lost interest a few years ago and haven't kept up but
there are surely other networks. Since these networks are all
connected over the network, it matters little where the other station
is as long as the other station is on your network. There are talk
group hierarchies for continents and nations and political
sub-divisions, etc.
Sadly, some folks don't seem to understand that the only *RF* part of
their QSO with that guy in Sydney, Australia, is from their radio to
their local repeater (which may be a hotspot connected to their home
network) and the same at the other end, and that the bulk of the
"propagation" is over the internet.
In fairness, I don't know how you'd log that in an accurate ADIF way -
DV, certainly, with DMR as a submode? Propagation via 4FSK and
internet? Not sure - I never log "HT type" QSOs so haven't thought
about it more than just now!

+ AA6YQ comments below

When logging DMR contacts I am not using a radio connected to the computer but simply manual adding a "NEW" contact.  DMR is a MODE that can be selected but I assume Tx band is left blank as well as signal reports.  I assume all normal QSL fields are logged.  Anything else I"m missing?

+ If your computer is not connected to a transceiver, the Main window's "Log QSOs" tab is the best way to log new QSOs. Check the "Optimize for real-time QSO entry" box (Configuration window, General tab, "Main Log QSOs options" panel) if you are logging new QSOs in real time; if you're recording QSOs after they are completed, uncheck that box.
