Hide some tabs in software

Question

I have some software but I don't have the source code.

I downloaded from www.manager.io

It has many tabs when you open it.

Is there any way to hide some tabs and windows of this software? The Tabs

I researched Software Engineering Tools and I came across the: CFF Explorer

https://ntcore.com/explorer-suite/ But I didn't know how to use it.

Is there any good tool that can do this?

Thank you
