Juniper TED (Traffic Engineering Database) update interval

I'm working on setting up BGP-LS on my network to monitor node and link state of our IS-IS L2 network. I am noticing that the TED does not update very quickly on IS-IS topology changes.

If I cut off a group of nodes, I see that they remain in the TED for up to 10 minutes before they are removed. I am using ACX1100 with JunOS 18.3R1.9.

Is this a tunable parameter, or is this just something I need to deal with?
