lvs rule
In general it is better to not touch any DRC/LVS deck.
You can simply waive the error if you're really sure that it is a fake error.
The DRC/LVS deck are text files. They can be plain text or crypted. In the second case you do not have any chance to modify them unless you have the password.
Moreover, there are many tools which perform DRC/LVS, each one with his own syntax. You need to find the proper user manual and start from there.
What you can do in practice, is to open the deck and find the violated rule (it is easy, just find the rule code in the file). You can try to understand all the performed layer operations, so you can exactly know where is the problem.
