Hi,

We use sieve with Cyrus. Cyrus does allow admins to authenticate as users
using the "PLAIN" auth_mech.  
https://datatracker.ietf.org/doc/html/rfc4616#section-2

I have written a php cli script that will generate and install the  
sieve script
for one user using the admin credentials.

As PLAIN is supported by dovecot this should work there too,
but you may need to tweak the script and your configuration.

If interested i can send you the script.

Kind Regards

    Michael Menge
