Bigfix Agent on Qradar Servers

Does anyone have the Bigfix agent installed on their Qradar servers. We have 7 Qradar servers, and for some reason the Bigfix agent is not installed on any of them. I don’t know anything about these servers. Are they virtual appliances that will not accept the Bigfix agent?

QRadar servers are very resource intensive. On this page https://www.ibm.com/docs/en/qsip/7.4?topic=installations-qradar-software they specify this:

Install no software other than QRadar and RHEL on your hardware. Unapproved RPM installations can cause dependency errors when you upgrade QRadar software and can also cause performance issues in your deployment.
