I found I could convert the error message to a string and then do a replace on it:

var error = Html.ValidationMessage("email")?.ToHtmlString();

if (!string.IsNullOrWhiteSpace(error))
{
    error = error.Replace("[login link]", "<a href=\"/login\">login</a>")

    @Html.Raw(error)
}

Try to use Remote validation and add a <a> tag in the validation message. Check the following code:

UserViewModel:

    [Remote(action: "VerifyEmail", controller: "Home")]
    public string Email { get; set; }

Code in the view:

        <div class="form-group">
            <label asp-for="Email" class="control-label"></label>
            <input asp-for="Email" class="form-control" />
            <span asp-validation-for="Email" class="text-danger"></span> 
        </div>

Code in the Controller:

    [AcceptVerbs("GET", "POST")]
    public IActionResult VerifyEmail(string email)
    { 
        //Generate the login url:
        string loginurl = string.Format("{0}://{1}/{2}", Request.Scheme, Request.Host, "Identity/Account/Login");
        if (_userService.VerifyEmail(email))
        {
            return Json($"Email {email} is already in use, click the <a href='" + loginurl + "'> here </a> to login.");
        }

        return Json(true);
    }
