New Deploy Tool For T2 Chip

https://github.com/munki/installr
"
installr is particularly useful with Macs with T2 chips, which do not support NetBoot, and are tricky to get to boot from external media. To use installr to install macOS and additional packages on a T2 Mac, you'd boot into Recovery (Command-R at start up), and mount the installr disk and run installr.
"
"
Usage scenarios
Scenario #1: USB Thumb drive
Preparation:
Copy the contents of the install directory to a USB Thumb drive.
Running installr:
Start up in Recovery mode.
Connect USB Thumbdrive.
Open Terminal (from the Utilities menu if in Recovery).
/Volumes/VOLUME_NAME/run (use sudo if not in Recovery)
Scenario #2: Disk image via HTTP
Preparation:
Create a disk image using the make_dmg.sh script.
Copy the disk image to a web server.
Running installr:
Start up in Recovery mode.
Open Terminal (from the Utilities menu if in Recovery).
hdiutil mount <your_bootstrap_dmg_url>
/Volumes/install/run (use sudo if not in Recovery)
"

Does anyone try this?
I don't have any device with T2 chip.

You don't need device with T2 chip to try this. Installr works on other Macs too.

I just need to be sure it can work on T2 devices.

Re: New Deploy Tool For T2 Chip

T2 devices can't netboot or boot from USB by default, but they still have Recovery boot mode. And when you are in Recovery, there is no difference between T2 or older devices - you have access to your system volume and you can modify it.

But yes, I don't have any T2 Mac yet, so I can't confirm actual experience.
