Can you turn off damage to buildings without creating new save?

[Actually_New_KSP_Player]

My 600 tonnes falcon 9 replica keeps destroying the launch pad when i'm retracting my landing gear so i can't properly test how stable it is. I couldn't find such option to turn off damage to buildings in cheat menu, so i'd like to know if there is a mod like advanced cheat menu or something like that. I don't really want to create another save because at some point I might want to return the damage or change something else, also all the launched crafts will be gone.

Hit ESC, click on the Settings menu, click on the "Difficulty Options" button at the top. The first page of settings that comes up has "Indestructible Facilities" on the left side.
