In OBS natively? No.
You could set the media source to have a hide/show hotkey though, then use a third-party tool like AutoHotkey to set up a looping macro to turn it on (via the OBS-assigned hotkey), wait for the duration, turn it off (again, via the OBS-assigned hotkey), then wait for however long you want it hidden before returning to step one, and loop the macro forever.
