Is it possible to manually TRIM the unused blocks (free space) for an existing APFS volume?

When migrating a MacBook from HDD to SSD, I did a block-level copy using dd. I believe for optimal flash lifetime and performance, it would be the best to issue a TRIM for every unused block in the new filesystem to inform the SSD controller (so it won't confuse my dd copy with a large file that occupies the entire disk). Is it possible to TRIM the free space manually for an APFS volume on macOS (like FreeBSD's trim or Linux's fstrim)? I've read that on HFS+, macOS's fsck has a TRIM pass, so TRIM can be triggered manually by running fsck -fy in single-user mode, and one should see a "trimming unused blocks" message. But it doesn't support APFS (I tried it and I didn't see any message about TRIM).
