Is it possible to mod the DLC switcher in the Main Menu?

I want to change the colour of the golden borders in the main menu on the left hand side, but this section seems like it’s in a different place to the others as the DLC selection was added later. Does anybody know where to start?

I actually was able to completely hide this switcher in my mod “Classic Main Menu - Ranked in 1 Click”. You could check my code there. And let me know if you have questions :slightly_smiling_face:
