Yeah, those servers are using many verifications due to a secure gameplay and billing purposes, however, they've reached the limit of dramatic stage of security system cuz they receive anytime complains from players just like "someone stolen my account or items etc..." Those complains leads the NCSoft to add even more security stuff but the negative point is that many players like you spending their time to support such servers, but for them as usual they ignore whatever players are saying for those stuff..... they do care to keep official alive whilst lineage 2 itself became "dead MMORPG game" in 2022.....
As for your question about avoiding few verifications, sadly you can't.... that's about the ncsoft's stuff to disable verifications.... The only thing you have to do is to request support through their official website and asking them about it...
