   For POST instead of PATCH use HttpMethodOverrideMiddleware

   public void Configure(IApplicationBuilder app)
   {
       app.UseHttpMethodOverride();
       app.UseMvc();
   }

   For PUT instead of PATCH create custom middleware

   public class MethodOverrideMiddleware
   {
   	private readonly RequestDelegate _next;
   
   	readonly string[] _methods = { "DELETE", "PATCH", "PUT" };
   	const string _header = "X-Http-Method-Override";
   
   	public MethodOverrideMiddleware(RequestDelegate next)
   	{
   		_next = next;
   	}
   
   	public Task Invoke(HttpContext context)
   	{
   		if (HttpMethods.IsPut(context.Request.Method) && context.Request.Headers.ContainsKey(_header))
   		{
   			var method = context.Request.Headers[_header].ToString();
   			if (_methods.Contains(method))
   			{
   				context.Request.Method = method;
   			}
   		}
   		return _next.Invoke(context);
   	}
   }

   and use it in Startup.cs

   app.UseMiddleware<CustomMethodOverrideMiddleware>();
