The tokens / HSMs I've used don't let you generate a key somewhere else and install it on the token. They insist on doing the key generation locally. That is, after all, part of the point of using a token - the key never leaves it.
Some tokens and HSMs support key backup and restore, e.g. Nitrokey HSM's DKEK share mechanism, but that's deliberately not open to "restoring" some arbitrary private key onto the device.
So this wouldn't make much sense for the pkcs11 engine, even if PKCS#11 provided an API for it.
