None of ViewComponent's methods are virtual so you cannot override them.

Do you mind to share how do you override the view components in nopCommerce through plugin? For example, if I would like to implement some modifications to "HomepageProducts" view component, what are the steps to copy the "HomepageProducts" view component into plugin folder and make nopCommerce picks up the modified version form the plugin?

You also done through plugin.

public class TestViewEngine : IViewLocationExpander  
{

    public void PopulateValues(ViewLocationExpanderContext context)
    {
        //nothing to do here.

    }
    public IEnumerable<string> ExpandViewLocations(ViewLocationExpanderContext context, IEnumerable<string> viewLocations)
    {

        if (context.AreaName == null && context.ViewName == "Components/OrderTotals/Default")
        {
            viewLocations = new string[] { $"/Plugins/Demo/Views/{{0}}.cshtml"
                }.Concat(viewLocations);

        }

        return viewLocations;
    }

after this you have to register view engine with the help of INopStartup.

May be INopStartup you have to inherit.  

for more information you have to look at this url.
