I have an install at new construction home where the electrician that installed a Siemens meter main did not leave much room on the right side to bring conduit in thru a knockout from an Enphase Combiner. The left side of the meter main has the barrier for bringing underground service wires up to the meter compartment, and it does not have a knockout. The service wires in this case come into the top of the meter main from overhead, and so that barrier compartment is empty.

I would like to punch a hole in the left side of this meter main, and mount the combiner to the left and bring conduit into the barrier compartment, and bring the conductors thru the barrier into the breaker area and land on a branch breaker. Attached is the PDF. Is there any issue with doing this? I have not looked at the meter main physically yet because the site is 90 minutes away. Has anyone installed one of these before and done something similar?

I toss those barriers then I do a OH service looks like the installer forgot. The set screw is in the meter section so you'll need to unseal and pull the meter to get it out.

This meter base is ringless, doesn't that mean the cover can come off without pulling the meter?

I believe you will find you can remove a retaining screw and push the barrier up into the meter compartment.

I see the screw in the meter compartment. My question is can I remove the meter compartment cover to access that screw without pulling the meter? The unit is ringless according to the documentation.

I have never tried that, you'd have to break the POCO seal to get the cover off.
When I need to do something 'non electrical' inside a residential meter socket for instance we get calls from a siding contractor often to remove the screws in a meter for new siding or brick work,
My boss will notify the POCO a few days in advance that its non-electrical in nature, no changes to wiring, no changes in load, and see what they say sometimes he has me meet a linman sometimes not.
With the old seals I could cut it my self, some newer seals you need a special 'key' tool the lineman has.
The diagram shows shows the one screw you need to remove:
