SD card failures in PowerEdge VRTX blade

I remotely manage a PowerEdge VRTX tower chassis with two M620 blades and an M630 blade. The Chassis Management Controller is reporting failure of both Internal Dual SD Modules in the M630. There is also an alert that Internal Dual SD Module redundancy is lost. All of the blades run ESXi and the chassis storage is shared with all three blades. The warranty expired and we have third-part hardware support on the unit.  The service manual says when replacing an SD card to go into system setup and check if the Internal SD Redundancy option is set to mirror or disabled and mentions the possibility of data loss in an SD card failure. I didn't setup this unit but think the alert indicates the redundancy is likely set to mirror. The manual then says to go into setup again after replacing the SD card and verify that the Internal SD Port option is enabled and Internal SD Card Redundancy is set to Mirror mode. I am very concerned as the hardware vendor says their FE will only replace the failed parts and said going into the system setup is the customer's responsibility. Is it safe or recommended to go into the setup and make these changes remotely through the iDRAC? I am also wondering if there are other steps needed to restore the SD card redundancy or if replacing the failed cards is all that is needed. I moved all VMs off the M630 as ESXi is reporting lost connectivity to the device backing the boot filesystem and says host configuration changes will not be saved to persistent storage. I don't think the M630 would survive a reboot in the current state and suspect that ESXi will need to be reinstalled after the SD card replacement. Does anyone have experience replacing SD cards in a PowerEdge server with a Dual SD module setup?
