Standard responsibility disclaimer applies, not recommended, may void warranty, may negate availability of Dell assistance, etc. But for others who are ok with these risks, and/or are out of warranty support period anyway, you now have the information necessary to get rid of the unnecessary warning.
Side note for Dell: there really should be a way to disable these non-critical, arbitrary warnings in OMSA. I've missed ACTUAL VALID warnings because i got used to seeing the non-certified warning triangle in OMSA. You shouldn't be "Crying Wolf" when it comes to things like server administration.
