Razer Chroma SDK Server is blocking port part 2

Hi there,

I'm using Razer Basilisk since yesterday.
After installing Razer software (Synapse), I recognized that the port (1337) I usually use for development is blocked.
Unfortunately it is the Razer Chroma SDK Server.

Is there a way to define which port it should use?

This problem has been postet before and still persists (/razer-chroma-sdk-server-is-blocking-port.51071/). Any chance of solving this issue?

I first noticed it when I tried to start a nodejs server at port 1337. It automatically changed to 1338 instead, because 1337 was in used. I used netstat to get the id of the process using the port and then tasklist to get the process name:
