Issues updating Latitude 5540's via DCU Universal

We utilize dell command update universal within our organization. Have never had issues getting our endpoints updated with DCU until now. For whatever reason our Latitude 5540's will not pull latest driver using DCU. Running manual scans or utilizing a script nothing is found. Newest release from dell support website is 1.12. I did read online that dell holds updates from DCU tell the following quarter? Is this the reason why? Seems odd as all other machines within environment update to current bios fine besides this model. I know the script is not the issue as we have utilized it to update 3/4's our org. Any assistance would be appreciated as running the individual bios exe has proven to be unstable with bitlocker.
