Main Menu Streamliner is a mod that can hide menu entry.
How to :
-Start the game with the mod placed in mod folder then go to mod/save folder and look for "mmstreamline_nodeconfig.lua" file
there remove the "--" on entries you wanna hide.
-If a menu entry is not in the mmstreamline_nodeconfig.lua file go to the main menu streamliner mod folder, open "dumpmenunodes.lua" and change "local dump_hidden_entries = false" to "true" delete the "mmstreamline_nodeconfig.lua" and restart the game or use relua mod.

Once you made your change to "mmstreamline_nodeconfig" restart the game or use the Relua mod

Mod is not made by me. I just updated it a bit and put it on github. If you wanna look at it.
