Is client-side hashing with Nitrokey HSM 2 not possible?

[Vampire]

We bought a Nitrokey HSM 2.
We put a SignServer instance in front of it.

Now I wanted to get signing with client-side hash computation working to minimize network traffic and work the HSM has to do.

With a PKCS#12 file and according worker this works fine.
But if I try to do the same with the PKCS#11 worker for the HSM and the NONEwithRSA algorithm, I get an error saying “No such algorithm: RSA/ECB/PKCS1Padding”.

Is this not supported using Nitrokey HSM 2?
