Answer

No, neither Fpolicy or Native auditing captures copy-offloads reads or writes. This is due to the use of the SMB operation IOCTL to facilitates the read/write process when leveraging copy offload rather than read or write operations. There is no option within the Fpolicy configuration for the file operation of IOCTL, so Fpolicy does not have a way to capture events related to IOCTL requests. Similarly, for native auditing SACLs are used to determine what access is audited. There is a portion of the ACE, within the SACL on the file/folder, the access mask that represents the auditing access, to which there is nothing to include copy offload.
