Can I use a Commandline?

Yes. You can use a commandline. You do so with switches.

But before you do you should fill in the settings through the GUI. This will let you do the signing easily with just this command:

ecs /p:[product.exe]


The available options are:

/p: - Where the file to be signed is located

/t: - the timestamp url - overrides value in settings

/n: - the program name

/c: - the certificate - overrides value in settings

/s: - the certificate password - overrides value in settings

/i: - information url - overrides the value in settings.

You should not leave a space between the switch and the value. Spaces is the way the commandline is split and then processed.
