dell e6540 RAID 0 mod?

a while ago i was testing if its possible to do a raid 0 with 2 samsung 850 500 gb evo ssd’s
but to my supprise i the raid 0 wasnt a option inside the intel raid setup.
so i just gave up but today i came across a guide on this forum for the e7440 where it was done by modding.
now i’m wondering if thats also possible with the dell e6540?
right now i am on the latest bios for this machine (it is possible to downgrade versions as its supported by this machine)
if anyone has any ideas that would be great!
thank you in advance

The mod used in the 7440 can be reversed. Same should be possible on the e6540 - have you attempted?
