No and there should be no such option.
However if you are not interested in the command to complete and its result, 
then you might run the installer in a cmd script and launch it with "start" so 
the install process detaches and WPKG continues even though the installation is 
still ongoing. You can combine this with scripting to wait for certain results.

For example a simple cmd script like this:

@echo off
:: Launch installation.
start "Installation" "install.exe" /silent-option
:: Wait for 30 seconds
ping -n 10 localhost >NUL
:: Terminate with success exit code
exit /b 0

This would make the cmd script wait for 10 seconds and then terminate with exit 
code 0 (success) no matter what the results of install.exe are or whether it 
terminated. You might extend this with some taskkill command to terminate 
install.exe if still running after a timeout.

Though all this is considered very very bad practice due to various reasons 
- You don't know the real installation status
- Installation might not have been completed
- Installation might ask interactively for some reason; perhaps some product 
features will not work

It would be much better to analyze why the installer actually hangs and prompts 
for interactive user input and solve this issue and fix it. WPKG is made to run 
silent installations and this installation seems to be clearly not silent. 
Consider enabling the "Interactive Services Detection" service to get notified 
about dialog boxes opened by WPKG commands. Then find a way to run the installer 
silently. If everything fails with the default installer, then you might have to 
re-pack the software in a silent installer. I had to do this on a couple of 
occasions and had good results with simple CMD scripts and self-extracing 7-zip 
archives. Alternatively contact the software vendor to fix the installer if it 
claims to be non-interactive/silent but still prompts the user interactively 
which is clearly considered to be a bug in the installer.
