My engine is out of the car so I can’t help with that aspect.
Here are a few pix that may help you visualize the process
This one (above) shows passenger side mount on engine just forward of exhaust manifolds
And - above - the driver side; a better view of the 4x mounting bolts.
The 3 most-visible can be accessed with socket/ratchet - the 4th is definitely to be attacked with a wrench (just visible to the lower-right of the rubber mount).
The next two show the sides of the engine:
I think you may be able to remove the rubber mount without removing the assembly. It is held in place with a single 9/16 bolt. It’ll be a tight fit to get in there to remove just the rubber mount.
You can buy left & right side mount heat shields or make your own. Here is a close up of home made shields. A single hole in it fits over the stud in the rubber and the shield is then pinched between the steel mount and engine side.
With these items off my engine I can provide any pix/close-ups you need
