Burmese egg incubation

Hi guys,
been lurking a while but have a few questions in regards to incubating Burmese eggs as have found conflicting info.
first time breeding burms (and any python for that matter), but have worked on much smaller projects over the years, to which I’ve always used vented tubs.
Would you recommend a sealed tub or ventilation in there? as its all a bit hit and miss with what i’m finding online, and i’m not sure what to roll with. She’s not layed yet but I want to make sure i’m all good to go for when she does.
Pairing for those who want to know, is female, hypo het granite, to a male granite, and a male ivory
