Machine can be changed freely at any time?

I am KRE
Node-locked license annual contract for 1 machine use

I contacted you with a question

I’m using it when developing using jenkins. First, I use the machine ID on my personal computer, and after testing, I’m going to move it from the company’s dedicated computer. Since I’m using one machine, I wonder if it’s possible to change it every time or if I can’t change it again if I register one machine

I want to know if the machine can be changed freely at any time?
