Have make Hyper-V VM guest and setup replication, there is 5 disks, 3 of them excluded from replica, but as i see on files system there is created HRL files for all disks of VM, even for excluded. After a replication period (5 sec) send difference for 2 disks of replication on replication server, excluded disks HRLs just deleting by system.

System is on SSD drive, on excluded disks placed temp files, it's double write operation on SSD.

On WS2012R2 there is no such problem.

Is there any fix for this?

    I see that you did not understand my question. I did not select disk (exclude it from replication), but hyper-v make mirroring the changes to a HRL file of excluded disk. On Windows Server 2012 R2 i did not seen that problem, it happens only on Windows Server 2019.
    I have resolve this problem on WS2019 by connecting physical disk to VM, instead of excluded VHDX, and this resolve my issue with unnecessary HRL files for excluded disks.
    But this is insane, to mirror write data for excluded VHDX in Hyper-V Replication.
    More insane, that i can't change path for mirrored HRL files, for example - on RAID0 HDD, instead of double writes on SSD, that killing lifespan of SSD twicely and reduce overall speed by growing latency of SSD...
