This recommendation is based on the Azure Security Benchmark, which is a policy initiative or group of policies that is included with Azure. The initiative is updated periodically.
This is one recommendation that I disagree with. I shared this with the MDE team and they seemed to agree. A more common recommendation is quick scans daily or weekly followed by full scans monthly (or only when manually requested).
You might attempt to modify the polity to better reflect your scanning preferences. You also have the option o make exclusions or turn the associated policy off completely.
