Is there any way to render Name value list field using rendering variant fields?

Depending on what you want to achieve. If you will use standard Variant Field you will see something like this:

for such field:

If you want to have a more fancy look & feel I would suggest writing your own Variant Token. A sample implementation can look like this:

public class ResolveNameValueList : ResolveVariantTokensProcessor
{
    public override string Token => "$nameValueList";

    public override void ResolveToken(ResolveVariantTokensArgs args)
    {
        string content = GetContent(args);

        if (args.ResultControl != null)
        {
            args.ResultControl.Controls.Add(new LiteralControl
            {
                Text = content
            });
        }
        else
        {
            args.Result = content;
        }
    }

    protected virtual string GetContent(ResolveVariantTokensArgs args)
    {
        string content = string.Empty;

        var field = args.ContextItem.Fields["List"];
        if (!string.IsNullOrEmpty(field?.Value))
        {
            CustomField customField = FieldTypeManager.GetField(field);
            if (customField is NameValueListField)
            {
                NameValueListField nameValueList = customField as NameValueListField;
                foreach (string key in nameValueList.NameValues.Keys)
                {
                    content += $"<div>{key}: {nameValueList.NameValues[key]}</div>";
                }

            }
        }

        return content;
    }
}

And registration:

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
    <sitecore>
        <pipelines>
            <resolveVariantTokens>
                <processor type="YOUR_NAMESPACE.ResolveNameValueList, YOUR_ASSEMBLY" resolve="true" />
            </resolveVariantTokens>
        </pipelines>
    </sitecore>
</configuration>

With such token, you only need to create a new Variant Token item and specify your custom token name:

This will give you:

Last note: Maybe this would be possible in NVelocity templates but do not go that path. If there is a different way (even if requires writing some code) to achieve something without NVelocty - go for it!
