for lyra you need to have your project in C++ mode so you can access the C++ classes from where the blueprints are derived from. many values are codded inside the C++ files and can be updated there
first try to search youtube and see if someone made a video on how to enable c++ in the lyra project.
if you don’t find it then use this old thread I’ve made but follow only my comments because some user posted wrong suggestions. but try this as last resort as is an older thread and I didn’t tried this method for the last unreal and lyra versions
