Need help with Feast achievement disable and Player spell level requirement

Dear Users!

I need help with some features.

How can I disable some Feast of Strenghts Achievements (for example: WoW’s 4-13th Annivesary) and Player spells.
For the Player Spells, I mean, how and where can I edit the auto-learned Spells on specific level (for example Hunter Disengage), and how to add missing spells form spell bar on fresh new characters.

Thank you so much for your help!

Still need help.

do you have information about this ?
