Unable to access connected router 192.168.8.1 when connected to tailscale (client) when another gl inet router is connected to tailscale

My current setup is having 2 gl inet routers (GL-AXT1800 and Flint 2 MT6000) connected to the tailscale network. When the client (connected to Flint 2) accesses 192.168.8.1, tailscale maps thatt to the GL-AXT1800 due to GL-AXT1800 enabling subnets! The only way to access Flint 2 is to disconnect tailscale which is not feasible since I have storage attached to the Flint 2 via its USB A port! Any solution/modification that I should make to Tailscale ACL route settings for this? Thanks!

The subnets of the two GL routers in the Tailscale network need to be set to different.
For example, Flint 2 is 192.168.8.1 and Slate AX is 192.168.10.1
