We can't support the RESTORE command with the replace flag.
This is mostly because of the support of graph virtual keys decoding. decoding virtual key will add to an existing key.
As a result when using RETORE replace the content of the restored key is add to the existing graph, leading to all sort of data inconsistency.

There are several options:

1. Remove the support of graph virtual keys
2. Replace RESTORE command with a dedicated new graph command, e.g. GRAPH.RESTORE
