if you can just trim down any conifer willy nilly
Many (most?) will not regrow from old wood, so if you butcher it, it'll look butchered forever.
Bird nesting season now so if I were you I would just embrace its privacy and wildlife value, until you can afford to get it properly removed.
Maybe grow a climber up it so you get some flowers

Ha yeah I get you. Just want it at least reduced in size for now, but don’t know if you can just trim down any conifer willy nilly
