Depending on many restrictions, yes.... you could have "wet venting" where the main soil stack acts as a vent also.
Operative here is many restrictions in the configuration... trap arm lengths/sizing, single floor etc etc.
Would need to know your exact layout to know if it even possible.... it does seem unlikely that the entire house (multi bath rooms and kitchen/washer.... etc could all be wet vented.....
Get up on the roof and determine your main vent and other vents.....
EDIT: Studor AAV venting is also a possibility depending on your jurisdiction.... although I think most jurisdictions that allow them, also require them to be accesable.... so you ought to be able to get to them or see them.
(Caveat.... I'm a GC not a plumber. If I do minor plumbing myself, I have to pull out my books and review anything but simple venting.)
Of course venting may be tied into other dry vents and projections thru the roof can be minimized.
