Hyper-V convert to direct disk

My 2012 R2 Server is running on 5 RAID6 HDDs + 1 spare (WD REDs). It's used as a storage server, with two Windows 8.1 Pro Hyper-V clients. The problem is that the disk access in general is kind of slow. So my idea is to move the windows to RAID1 SSD, and move both Hyper-V clients to another RAID1 SSD, and keep RAID6 HDDs just for users files storage.

Both Hyper-V setup as dynamic disk files. Is there a way to convert them and run them as direct disk access from SSD divided into two partitions?

Thanks so much for any help.
