Cyber Security is a major issue today. I'd be very careful about what you disable.
This is why out of the box I normally turn on all security features that come with the security appliance (if licensed). You just have to be aware of limitations and potential bottlenecks that can be created with these additional security features,
The Ubiquiti USG at a customer location, that I mentioned was getting tons of dropped packets and very poor audio. If you look at the link below, you see that the USG throughput drops from up to about 900 Mbps with IPS disabled, down to only 80 Mbps with it enabled.

The VoIP phone service had been working fine for a couple of years until the customer upgraded their Internet speeds.
