You can swap out the entire interactionmode logic with a custom interaction mode, you could copy the implementation of the arrow interaction manager and customize what you want to change. There are some details here: https://rct.lukasbach.com/docs/guides/interaction-modes#custom-interaction-modes

Something like this:

function App() {
  return (
    <UncontrolledTreeEnvironment
      dataProvider={new StaticTreeDataProvider(longTree.items, (item, data) => ({ ...item, data }))}
      getItemTitle={item => item.data}
      defaultInteractionMode={{
        mode: 'custom',
        createInteractiveElementProps: (item, treeId, actions, renderFlags) => ({
          onClick: e => {
            actions.focusItem();
            if (e.shiftKey) {
              actions.selectUpTo(!e.ctrlKey); // Customize here
            } else if (isControlKey(e)) {
              if (renderFlags.isSelected) {
                actions.unselectItem();
              } else {
                actions.addToSelectedItems();
              }
            } else {
              actions.selectItem();
              if (
                !item.isFolder ||
                this.environment.canInvokePrimaryActionOnItemContainer
              ) {
                actions.primaryAction();
              }
            }
          },
        }),
      }}
      viewState={{
        ['tree-4']: {
          expandedItems: ['Fruit', 'Meals'],
        },
      }}
    >
      <Tree treeId="tree-4" rootItem="root" treeLabel="Tree Example" />
    </UncontrolledTreeEnvironment>
  );
