Not that I know of. You can have the old tiefighter-cockpit overlay,
which probably reduces the amount of shown 3D-graphics,
but the battle scene itself will be loaded anyway.

How can I do that??

Warning: XML editing ahead.

Step 1: Find the file Gamesonstants.xml, which should be in
\steamapps\workshop\content\32470\1770851727\Data\Xml
Backup the file in case you change your idea or accidentally do something wrong

Step 2: Find the line
<Demo_Attract_Maps>MenuSpaceSunsetMountains.ted, MenuSpaceHapes.ted, MenuSpaceVulcanicPlanet.ted</Demo_Attract_Maps>

Step 3: Change it into
<Demo_Attract_Maps></Demo_Attract_Maps>
which is deleting everything in the middle, and save the file

This should give you a completely black menu background.
Please make sure you keep a backup of the original file, because if this goes wrong your game may die with it.

Confirmed.
If you search for an editor, I use notepad++ for most editing.
