Change checksum hash algorithm used

Is there a way to set the --checksum hash algorithm used when syncing a source and destination to something like BLAKE3?

hello and welcome to the forum,

rclone does not support BLAKE3.

rclone supports the hashes used by the storage system.
gdrive and s3 use MD5, so rclone uses that.
ftp does not support hash.

ftp does not support hash

To confirm if I was to do a sync directory between 2 local computers on the same network is rclone unable to do checksum then?

rclone should checksum when the source computer and dest computer are on the same network.
tho it might depend on the protocol, smb/samba, sftp, webdav or what?

here is a log snippet, source and dest are local on same machine, should get same result between two machines.

rclone sync ./source ./dest -vv
DEBUG : rclone: Version "v1.60.1" starting with parameters ["rclone" "copy" "./source" "./dest" "-vv"]
DEBUG : file.ext: md5 = d41d8cd98f00b204e9800998ecf8427e OK
INFO  : file.ext: Copied (new)
