How to cache the user pin for GPG signatures for some time?

Nitrokeys
1

I currently have to enter my card pin for every single signature. Since I sometimes do hundreds of signatures in batches, this isn’t really viable for me. For my Nitrokey 2 Pro this “just works” and I don’t really worry about it. With my new Nitrokey 3A Mini, it won’t cache it at all. How can I configure this?

gpg —card-edit
admin
forcesig

forcesig toggles the requirement to enter the User PIN everytime and it is the default on Nitrokey 3. When disabled, it will ask once per powercycle of the Nitrokey.
