ASN Block - Firewall

Is there a way we can block entire ASN network instead of ip addresses
Like i want to permanently block AS4134 CHINANET-BACKBONE

Can someone please guide.

These Chinese hackers are going absolute brutal with daily 30-50 attacks from different ip’s. Even though we use precautions… We want to keep our server’s safe.
