any idea about disabling Add comment option for some blocks?

yes that would be great. Till then I have disabled the context menu for this define block. Using: this.contextMenu=false;

This driver works to get values on serial monitor, https://github.com/kobolt/usb-can But I am more interested in next step, i.e., using can0 interface

Ok, no problem. I have the kernel installed. It is 6.x, which, in my case, is already installed on Ubuntu 22.04
