You could make the system priority hot water and then set the CH flow temp to suit the UFH and rads.
Under Floor Heating Temperature

Is that by boiler setting or change to pipework?
Right now, my boiler does both under the one setting. If I press the water button on the boiler I just get dashes, plumber who commissioned it confirmed it’s running both ch & hw under one temp setting.
I guess demand is created by any of three systems, hw, ch and ufh, all on separate valves, and the boiler sends heat out from a single point that divides off.

Look up priority hot water with your boiler. It would need some pipework and component changes.
Not exactly sure without research but it may allow you to have temp for DHW different to that for CH... your boiler may or may not support this... You could also look into CCTs (close coupled tees) for the UFH supply.
