How to disable Hotkeys on Mame2014/Mame2016-Cores?

how can i disable Mame-Hotkeys (like Test, Service, Reset, Menü, OSD Frameskip)? whit my Lakka-Device they are all mapped to the Controller (L2/R2/L3/R3…) and can pressed accidentally ingame very easy. how can i change that, unfortunaly there is noInput-Settings or Remap-tab for that cores.

Not sure how is a Lakka setup, I use it in Windows mostly, never used MAME core in Android. In Windows, you gotta press / to access MAME built-in menu, which is TAB in standalone version, then you reach the general inputs and change that or leave them empty, like reset, etc.

i will wonder if it can be set over RA Quickmenu or something. No way for that ?

As far as I know, we can’t, unless it was added in the core/quick menu controls or options and making us able to change such keys. For now, if you can simulate a keyboard or even plugging a real keyboard in your Lakka device and change that, would solve this, I changed these controls once and never needed to change anymore.
