Dry Verge Bottom tile removal

[Mark 9002]

Hoping I can get some advice
I have to remove this bottom dry verge tile to replace the wood ( or cap over ) behind it.
I know that when installing these they are started from the bottom and interlock upwards.
Its a Marley type from approx 30 years ago ( that's the age of the house anyway ) In the garage I found a couple of tiles that must have been left over so have attached this pic as well. Is there any way I can get just this bottom dry verge removed. I have a multi tool. Would it be possible to slide this under somewhere and nip the nails off,( where ever they are )
Any Ideas pls

You’ll be able to slide a 9mm capping board under that. The front will be loose and the nail will be in the lath under the next dry verge. you need to extend the guttering further out when finished.
