Customize image resizing

How can I update these properties if I'm using the grapesjs-preset-webpage?

You can always update a component type (but do it as a plugin)

editor.DomComponents.addType('image', {
	model: {
		defaults: {
			resizable: {
				  tl: 0, // Top left
                  tc: 0, // Top center
                  tr: 0, // Top right
                  cl: 0, // Center left
                  bl: 0, // Bottom left
			}
		}
	}
})

You can use this options for the resizable property of components
