Enabling aggressive blocking is possible on a global level (for all websites), as well as on a per-site basis.

brave://settings/shieldsin the address bar.
Trackers & ads blocking→
Enabling aggressive mode on a per-site basis:
- Click on the Brave Shields icon in the address bar while you’re in the website you would like to have aggressive ads & trackers blocking.
Trackers & ads blocked (aggressive).
As per @sampson
Incredible, it appears as though Google is allowing malicious sites to take-over Brave search terms to target the vulnerable. Consider this site, which uses a homoglyph in the URL to look official. The download is flagged as malicious by several security vendors. Please report!
If you enable Aggressive blocking in Brave (via the shields), you won’t see these potentially-dangerous SERP ads on Google. While making changes, replace Google with search.brave.com for a better experience altogether
