Assuming the OP can do OLCI for the DXB flight they just need to get to Gate before it closes as Qatar will check any bags through if asked at the origin - as to see the check in supervisor if there is any query or pushback.
If the OP is checked through from IAH all the way to DXB, which is likely as they have bags, the system may in fact flag them as a connecting passenger. Check-in staff have the ability to manually locate an onward connection, which is how they print BPs even for other airlines. On the DOH side, if/when they look at the connections list, it's not immediately apparent that a passenger is connecting on separate tickets. Whether they choose to provide protection in the event of a misconnect is, of course, a different story.
I'll concede that I'm not 100% sure this is how it's done with QR, but it's common on other airlines that use Amadeus Altea.
