Pressing the Update SDK button will automatically install the git version. Navigate to Edit - Preferences... - Add-ons - Armory to find the Update SDK button. Before updating, you may need to install Git first. When installing Git on Windows, select Use Git from the Windows Command Prompt option.

Afterwards, select Update SDK and inspect the command line for details - the process should take just a minute. Once done, restart Blender for changes to take effect. If something goes wrong, use Restore SDK button to revert the changes.

• Install Git.
• Pick a location for cloning the sdk and open a terminal/command line here.

git clone --recursive https://github.com/armory3d/armsdk
cd armsdk
git submodule foreach --recursive git pull origin main

• In Blender, navigate to Edit - Preferences... - Add-ons - Armory. Uncheck Bundled SDK and set path to the newly cloned armsdk folder.

cd armsdk
git submodule foreach --recursive git pull origin main
git pull origin main
