Acrobat Pro DC combining files processing in background?

[TIF doctor]

Using Acrobat Pro DC (2021, continuous release), combining files into a PDF, after clicking the "Combine" button, the Acrobat window constantly forces itself to be in focus. Switching to another window, the Acrobat window forces back on top every time it moves to a new file that it's combining.

It's a real detriment to productivity when I can't do anything else meanwhile, even on a second monitor.
This is especially annonying when processing hundreds of image files.
Is this something that can be changed?
I need it (any probably thousands of other users) to run in the background and only tell me when it's done.

Use a program which can combine files in the background.

Unfortunately, you can't. Adobe specifically designed Acrobat so it can't be used as a background tool.

Acrobat 9 and older versions can run in the background.

This feature has been removed since Acrobat X.
