Rest Overclock Settings Without Losing RAID 5 Array

I recently used the Asus EZ Tuning Wizard that is a part of the Asus z170-a BIOS to overclock my Intel Core i7-6700k. I'm not happy with the temperature tradeoff that resulted from the overclock and now I'd like to bring everything back to the system defaults. Loading the default BIOS settings will set all of my drives back to ACHI mode. I'm concerned that loading these default settings will cause my RAID 5 array to be unrecoverable. Is there a way to safely load the default settings without destroying the array?

I've done a good bit of research on this and not had much luck. I don't want to clear the CMOS because that will also result in all drives being put back in ACHI mode. I've seen some people report that you can clear the CMOS and once you put the drives back in RAID mode the system will "re-discover" the drives, but I find that hard to believe. Why can't the EZ Tuning Wizard have an easy off button?

System Specs:
Intel Core i7-6700k
Asus z170-a
Samsung 850 PRO SSD (for operating system, not part of the RAID)
Western Digital Black Performance Drives [x3] (all part of the RAID 5 array)
G.Skill Ripjaw V DDR4 Ram (4x8GB sticks at 2133Mhz)
ASUS Strix GEFORCE GTX 970

I assume you're using software RAID, and that your system is stored on the array.
This is not advised for reasons that you are discovering.

You can reset to defaults, load up the bios and set your storage settings as you'd like before the system ever even attempts to boot, just save & exit, and enter BIOS on restart.

Additionally: it will fail to boot, not destroy your array. No action will be taken by the PC without you telling it to.

Thanks for the response. Correct, the array is a software RAID. In my research leading up to creating the array I found that in most cases a separate RAID controller is not needed unless there is a large number of drives in the array, or if it is being used for enterprise data solutions. My array is only used as a storage system, Windows 10 lives on an SSD that is not part of the array. I understand that I can load the default settings and launch back into the BIOS to change the drives back to RAID, but will this create a new RAID array that will attempt to write over the one that already exists?
