You may have good reasons, but I'll note for other readers that the NetBox documentation takes a position against doing that:

> "Serve as a "Source of Truth" - NetBox intends to represent the desired state of a network versus its operational state. As such, automated import of live network state is strongly discouraged. All data created in NetBox should first be vetted by a human to ensure its integrity. NetBox can then be used to populate monitoring and provisioning systems with a high degree of confidence." - https://docs.netbox.dev/en/stable/introduction/

and

> "ultimately the onus falls to a human operator to assert what is correct and what is not. For example, NetBox can validate the connection of a cable between two interfaces, but it cannot say whether the cable should be there." - https://docs.netbox.dev/en/stable/getting-started/planning/

Monitoring systems reflect the way your network is; ideally NetBox holds the admin side of the way your network should be - from your contracts, services, business agreements - and if the real state differs, you bring the real state into line with NetBox.
