Is there a way to disable a marker or a polygon to be draggable in leaflet-geoman?

As the title says, I have a set of different markers and polygons on a map. All I want to do is to disable the markers and the polygons I create on the map to be dragged and only make circles draggable. As far as I read the documentation, there's no way to do that in drag mode.

You are right, there is no way to disable the drag.

But you can use this workaround:

function enableDrag(){
    map.eachLayer((layer)=>{
        if(layer._dragDisabled){
            layer._pmTempLayer = false;
            layer._dragDisabled = false;
        }
    });
}

function disableDrag(){
    map.eachLayer((layer)=>{
        if(layer instanceof L.Circle){
            layer._pmTempLayer = true;
            layer._dragDisabled = true;
        }
    });
}

When a layer has the property _pmTempLayer it is filtered out in the drag function.
