This is one way to do it, you will have to know the name of the material and name of the texture property.

Material foundMaterial = null;
foreach(Material mat in renderer.materials)
{
	if(mat.name == "my-material")
	{
		foundMaterial = mat;
	}
}
		
if(foundMaterial)
{
	foundMaterial.SetTexture("propertyName", myTexture);	
}

To find the property name of your texture, look at your shader script. Check highlighted.
