Aopen 27SA2 EBI -- how to access the SM?

I picked this one up to replace a cracked HP 24" VGA/HDMI that was also 1080p as the HP was BER due to the cost of 1080p monitors at a yard sale after pursuing a few and getting lucky for once. I checked the DOM and it is from 2023 so it isn't all that old so I think the hours will be low, but is there an accessible way to get into the SM on these Aopens? The newer Samsungs with the firmware update USB port no longer have this, but this Acer doesn't have clear signs it has the issue where you have to use a dongle to check the SM.

Can't find the SM for this thing, or a tutorial.
