Howto - avoid brute force re-silvering of already existing data on disk?

is there an option available where a disk with the same user data from an existing pool can be exchanged for a pool disk without a complete re-silvering process?

my setup is this:

- encryption on
- raidz1

example

disk 1
disk 2
disk 3

- zfs replace disk 3 with a new, blank disk 4

- now I want to exchange disk 4 with disk 3 - How can this be done without zfs replace - re-silvering all the content? No new user data has been added to the pool.


edit:
