2011 Timing belt cover removal - without pulling rad?

First Forum question from a brand new to Subaru owner
Is there any way to remove the timing belt cover (to solve an oil leak identified by dealer as timing belt cover) without pulling rad etc. I am not trying to get any anything else but the cover gasket.

From what I have seen, it looks like all needs to come out but was hoping an experienced forum user might have a suggested shortcut

Thanks
