You can change the RetryStrategy by setting FileTools.DefaultRetryStrategy. You’ll want to do something like this:
// Change from default of 3 retries to 10 retries using default 500 milliseconds base interval.
FileTools.DefaultRetryStrategy = RetryStrategy.ExponentialBackoff(10);
Or set it to something completely custom if you want.
That said, I don’t know if this will solve the problem. The draco wasm error in OP doesn’t seem like it can be caused by a file not downloading due to retry failing.
