Hi @williamews
I hope you are doing well today.
Defender doesn’t have any rate limiting lockout features except for 404, IP Banning and login attempts features:

To fully protect site against DDoS Attacks you should consider WAF (if your hosting supports this) and CloudFlare solution. You can read about this here: https://wpmudev.com/blog/ddos-protection-guide-how-to-help-protect-your-wordpress-site-from-attacks/
