1) Yes but you have to create them with the event editor.
2) You have to edit the PlayerBox.json (.\client\resources\gui\layouts\game\PlayerBox.json) search the line "MPBackground" and change "Disabled": false, "Hidden": false, to "Disabled": true, "Hidden": true,
then search the line "MPBar": and change "Disabled": false, "Hidden": false, to "Disabled": true, "Hidden": true,
after search the line "MPTitle": and change "Disabled": false, "Hidden": false, to "Disabled": true, "Hidden": true,
last thing to hide is the mp label, search the line "MPLabel": and change "Disabled": false, "Hidden": false, to "Disabled": true, "Hidden": true,
