If I sign up for Advanced Plan, can I use the watermark as "blank"? I can use it without the watermark?

Hello!
Thanks for the great service!

I have a question about watermarking.
If I sign up for Advanced Plan, can I use the watermark as "blank"?
I can use it without the watermark?

I really want to use this great feature in my client work!
But my client doesn't like the watermark itself.

I'm sending this through the translate function, sorry if it's not clear.
Looking forward to hearing back from you, thanks!
