If it's just access to the outer cover you want, then removing the mirror plate won't be an issue - no glue needed.
The mirror is stuck to a plastic plate with mouldings that engage with the movement mechanism, when you un-clip it the plastic backing plate and mirror glass come away as one piece and stay together, the movement mechanism stays in the mirror, the heating wires need unplugging. It all goes back together the same way.
There's two lugs at the top and two friction clips at the bottom - pretty much exactly the same as when I changed the glass and skull cap on our Mazda. I just used fingers but in this video for a similar year Accord they use a screwdriver as a lever to remove the mirror plate.
https://www.youtube.com/watch?v=JreAaULZ1_AAlso goes on to show further dismantling of the mirror which should be very similar although I think you can ignore the mid section of the video as there should be no need to remove the whole unit like this guy did.
When I put the skull cap on like this guy I had to smack the two sides to get the minute gap to close.
