Change mnemonics (alt) key on Linux

On macOS there is registry option allowing to use ctrl - alt rather than option as mnemonics activator key.

Is there such possibility on Linux? I would like to use mnemonics in controls with ctrl + alt, rather than alt alone,

Right now, when I have some editor shortcut with alt key, like alt+D, if there is the same mnemonic available on the window in foreground, i can't activate it - editor shortcut takes precedence.
