You can format the title but there is no any option for the alignment of the filter list.
Thanks and regards,
LIke many things, while this is not directly possible via the filter formatting options, you could workaround that by using a worksheet with a text list with an action filter, acting as a filter the user interacts with (be sure to turn off the tooltip if you go this route).
Reach out if you have any questions or would like to see an example.
Best of luck!
