My question is if it is possible to disable T register duplication on HP-41C because I don't need this feature and I find it a bit annoying. In the user manual I couldn't find any useful information. I am sorry for my english.

It's a fundamental feature of all the HP RPN calculators with a fixed size stack. There are other HP calculators ("RPL" calculators such as HP 28/48/49/50 series and HP Prime in RPN mode) that have a stack that grows and shrinks with no duplication of the "top" element.
