The page linked in my comment states that they are not currently accepting unsolicited proposals, but I agree the FAQ makes it sound like they are open to being contacted. My guess is there probably isn’t a clear cut policy and that they just want to avoid setting an expectation that they will evaluate everything sent their way.
Aren’t OpenPhil? https://www.openphilanthropy.org/giving/how-to-apply-for-funding#Can_I_apply_for_a_grant
They specify that they have low expectations for unsolicited proposals, but it’s possible to contact them about it.

Will send them a message, thank you :)
