How to build Tailscale package using SDK without building whole kernel?

For Developers
1

I am trying to build Tailscale v1.76.6 using 24.10-SNAPSHOT SDK as per instructions at https://openwrt.org/docs/guide-developer/toolchain/using_the_sdk . However since Tailscale depends on kmod-tun package, the SDK tries to rebuild the whole kernel. How do I instruct SDK to use existing binary packages from the package feeds for dependencies?

Use imagebuilder or download package?

Tailscale pkg not updated to v1.76.6 in 24.10 repo yet.

Plus I am just trying to learn how to build a SINGLE package using the SDK.
