I would simply ask upfront if they’re open to hiring over 40 and/or hiring with a disability (and then mention I’m not litigious and simply don’t want waste their time if they aren’t looking for that, no hard feelings). I actually had a few places admit they are not going to hire over 40 + a disability after I made it clear I have no intentions to sue.
That's pretty stupid on their part, considering you're not permitted to break the law because the aggrieved party is "ok with it". This is typically a civil rights issue handled by government enforcement
