Run Archival Node, Non-Syncing, Frozen State

[hub-il]

Describe the bug
With the size of the P-Chain at almost 20TB we are trying to partition out the Avalanche database so that older blocks can be stored on cheaper disk. We would like to run a node where the RPC is available but the node is no longer syncing, so that the node is effectively frozen at that point.

It appears that based on our configuration, the bootstrapping phase never ends. We get the following when we try RPC calls:

API call rejected because chain is not done bootstrapping

We have tried a number of configurations without success. Your help on a working configuration would be greatly appreciated.
