You need to go to the X4 Mod, then go to Config in config you find a lot of cfg files. The one you need is playercontrol.cfg.
You can adjust settings in there, look for this part:
//******************************************************************************
// Forced clientside dvars
//******************************************************************************
// This feature allows you to control the clientside dvars
// 0 = disable
// 1 = enable, force once (default)
// 2 = enable, force every 5 seconds
set ex_forcedvar_mode "2"
// Grenade indicator
// 0 = disable (default)
// 1 = enable
set ex_forcedvar_nadeindicator "1"
// Crosshairs
// 0 = disable (default)
// 1 = enable
set ex_forcedvar_crosshair "1"
set ex_forcedvar_redcrosshairs "1"
set ex_forcedvar_crosshairnames "1"
// Hint for climbing walls and fences
// 0 = disable (default)
// 1 = enable
set ex_forcedvar_mantlehint "1"
