Set ENCRYPTION_KEY in existing installation

Due to a bug in InvoicePlane the ENCRYPTION_KEY was not set during installation. Is it possible to set it on an existing installation without breaking anything? Thanks!

I do know that thr problem of encryption key not being set during setup is resolved with Beta-3 that is on its way
