rclone failing with "AccessControlListNotSupported" on cross-account copy -- AWS CLI Works - amazon-s3

Question

Quick Summary now that I think I see the problem:
rclone seems to always send ACL with a copy request, with a default value of "private". This will fail in a (2022) default AWS bucket which (correctly) assumes "No ACL". Need a way to suppress ACL send in rclone.
Detail
I assume an IAM role and attempt to do an rclone copy from a data center Linux box to a default options private no-ACL bucket in the same account as the role I assume. It succeeds.
I then configure a default options private no-ACL bucket in another account than the role I assume. I attach a bucket policy to the cross-account bucket that trusts the role I assume. The role I assume has global permissions to write S3 buckets anywhere.
I test the cross-account bucket policy by using the AWS CLI to copy the same linux box source file to the cross-account bucket. Copy works fine with AWS CLI, suggesting that the connection and access permissions to the cross account bucket are fine. DataSync (another AWS service) works fine too.
Problem: an rclone copy fails with the AccessControlListNotSupported error below.
status code: 400, request id: XXXX, host id: ZZZZ
2022/08/26 16:47:29 ERROR : bigmovie: Failed to copy: AccessControlListNotSupported: The bucket does not allow ACLs
status code: 400, request id: XXXX, host id: YYYY
And of course it is true that the bucket does not support ACL ... which is the desired best practice and AWS default for new buckets. However the bucket does support a bucket policy that trusts my assumed role, and that role and bucket policy pair works just fine with the AWS CLI copy across account, but not with the rclone copy.
Given that AWS CLI copies just fine cross account to this bucket, am I missing one of rclone's numerous flags to get the same behaviour? Anyone think of another possible cause?
Tested older, current and beta rclone versions, all behave the same

Failing RClone Config
type = s3
provider = AWS
env_auth = true
region = us-east-1
endpoint = https://bucket.vpce-REDACTED.s3.us-east-1.vpce.amazonaws.com
#server_side_encryption = AES256
storage_class = STANDARD
#bucket_acl = private
#acl = private
Note that I've tested all permutations of the commented out lines with similar result
Note that I have tested with and without the private endpoint listed with same results for both AWS CLI and rclone, e.g. CLI works, rclone fails.
