Are the -u and -m flags exclusive or they can work together?

[netherlink117]

After some videos interpolated I got that question... Since I am runing a batch script with the next command:

rife-ncnn-vulkan -v -u -m "rife-v3.1" -f "%%06d.png" -o "%workspace%\interpolated" -i "%workspace%\original"

It made me wonder if the -u flag would use the model rife-UHD and exclude the use of the model described by the -m "rife-v3.1" part... Also, which one should I use for UHD videos if they are actually exclusive?
