MMH5.5 - Heroes of Might and Magic 5.5

Good afternoon!
I have two questions.
I wanted to open the map in a single-player game (to see what artifacts are in the center), but I can't use the tilde key to bring up the console to enter a cheat code to open the map. The tilde key doesn't work. When playing without a mod (although I checked this a long time ago), it worked, but with the mod, there's simply no such function. Is there a way to fix this?
Or, can you suggest another way to open the map? I'm not picky.

And my second question is: how do I disable the generation of mixed creatures on the map for a single-player playthrough? On pages 93-94, there's a description of a method:

• open with editor <game folder>/data/MMH55-Settings.pak
• find in file H55_GenerateMixedStacks = 1;
• change it to H55_GenerateMixedStacks = 0;
• save file and try new game.

What does this mean? Can you show a video?

But when I open MMH55-Settings.pak, I only see a file in lua format.
What do I need to do to solve this problem?
