Can it be changed?

All Sidebar controls have icon property. If you want to use real image, try customHTML control. See example:

https://docs.dhtmlx.com/suite/samples/sidebar/02_configuration/03_custom_html.html

In this example icon of control changed by setting new value to icon property:
sidebar.data.getItem("toggle").icon = "mdi mdi-menu";

But standard way to change any settings of control – use update() method of TreeCollection API:
sidebar.data.update("toggle", {icon: "mdi mdi-menu"});
