ultegra r8000 routinely works with 50/34 cranks, so one would think it should work with a 44. and even if it is a older frame 52/42 was common, so again 44 should not be a problem
how old is the frame, what came on it originally for components ?
Shimano says that 46T is the min allowable large chainring for the FD-R8000. See specifications section at
https://bike.shimano.com/en-EU/produ...D-R8000-F.html
Shimano RD's seem to be rated pretty conservatively re: min/max cog specifications, but I'm not sure how true that is of their current FDs.
Edited to add: apparently you posted your follow-up comment while I was drafting the above.
