I would like to downgrade and remove worker subscription

I would like to downgrade and remove worker subscription but stucking with this issue as below.

when I try deleting worker; I get error (Code: 10086) cannot delete as its linked to durable object
when I try deleting durable object?, (you guessed it) script still in use by a durable object namespace or service binding (Code: 10064)

Some help here please? Should be easier way or allow freeze worker if subscription not desired.
