Recover data from DELL EMC VNX 1600e

I have a VNXe 1600 storage that burned the controllers and I have no way to replace them. I have 5 disks in RAID 5 of 600GB each and 2 disks in RAID 1 of 1.2TB each. I would like to know if there is a solution to recover the data outside of a data recovery company, as they are charging too much.
