How do I stop a group from changing its location coordinates when I move the node inside

Below given is my group template. I want to disallow moving of particular groups which I am able achieve with movable property binding. But when I move any node which is inside the group, diagram automatically adjusts the groups location according to the internal node’s new location. I would like to implement a functionality in which diagram allows moving the internal node inside the group without changing the group’s location. How can I implement it?

$(
            go.Group, "Auto", {
                movable: true,
                subGraphExpandedChanged: function (group: go.Group) {
                    genericService.adjustOverlap(group);
                }
            }, new go.Binding("movable", "AllowMove"),
				new go.Binding('location', 'Location').makeTwoWay(go.Point.stringify),
			$(go.Shape, this.getShape("TrustBoundary"), { strokeDashArray: this.getStrokeDashArray("TrustBoundary") },
				new go.Binding('desiredSize', 'size'),
                new go.Binding("fill", "BackgroundColor"),
                new go.Binding("stroke", "isHighlighted", function (h) { return h ? "red" : "black"; }).ofObject(),
                new go.Binding("stroke", "BorderColor"),
                new go.Binding("strokeWidth", "BorderThickness")),
            $(go.Panel, go.Panel.Table, { name: "panelRegular", defaultAlignment: go.Spot.Center,alignment: go.Spot.TopLeft },
                $(go.RowColumnDefinition, { row: 1 }),
                $(go.RowColumnDefinition, { row: 2 }),
                $(go.Panel, go.Panel.Horizontal, { row: 1, column: 0, margin: 2, stretch: go.GraphObject.Horizontal },
                    $("SubGraphExpanderButton", { alignment: go.Spot.Right, margin: 5 }),
                    $(go.TextBlock, { alignment: go.Spot.LeftCenter, editable: editNodeText, margin: 5, font: "bold 18px 'Open Sans',sans-serif", portId: "T", stroke: null, fromSpot: go.Spot.Default, toSpot: go.Spot.Default, toLinkable: true, fromLinkable: true, cursor: "pointer", textValidation: currentInstance.okName }, new go.Binding("text", "FullName").makeTwoWay(), new go.Binding("stroke", "TitleColor"))),
                $(go.Placeholder, { row: 2, column: 0, margin: 2, alignment: go.Spot.TopLeft, padding: 5 }, new go.Binding("background", "BackgroundColor"))),
            params,
            new go.Binding("isSubGraphExpanded", "isGraphExpanded").makeTwoWay(),
            new go.Binding("computesBoundsAfterDrag", "letsNodeOut"));
    };

Your Group template includes a Placeholder, so the group’s location will definitely depend on the locations and sizes of its member nodes.

But you could limit how far the user can move a node by setting its Part.dragComputation property. See, for example, the stayInGroup function that is used in the Swim Lanes sample, https://gojs.net/latest/samples/swimLanes.html.
