Change IP for from the SD Card?

I’ve recently done a big network change and implemented vlans in my house, and as a result the network configuration for HassOS running on a Pi4 is unreachable. This was expected, but I figured I’d be able to remove the sd card and just change a file somewhere to get it the new information, and that isn’t as easy as I thought.

Is that possible? It was fully up to date before I pulled it offline. If necessary I can probably plug in an HDMI and kb, but I wanted to know if there’s a simple way to fix it first.
