How to install macOS Tahoe 26 beta on MacBook Pro?

My MacBook Pro (16 inch, 2019) is supported by Tahoe 26 and I want to trying macOS Tahoe 26 before public available.

This Mac is currently running macOS Sequoia 15.5 and still not receiving update to macOS Tahoe. How can I install the beta on my Mac? Should I create a USB installer or run the upgrade assistant app?

Thanks
