To install async drivers using esxcli and offline bundle async driver zip file:

Extract the contents of the async driver zip file.
Identify the offline-bundle.zip file(s).
Log in to the ESXi host using the vSphere Client with administrator privileges, such as root.
Using the Datastore Browser, upload the offline-bundle.zip file(s) to a datastore in the ESXi host.
Enter the host into maintenance mode.
Log in as the ESXi console root to by using SSH or iLO/DRAC.
Copy the offline-bundle.zip file to a datastore accessible by the ESXi host using this command:

cp offline-bundle.zip /vmfs/volumes/datastore_name
Run this command to install the drivers using the offline bundle:

esxcli software vib install -d /path/offline-bundle.zip

Note: This command requires an absolute path.

For example:
esxcli software vib install -d /vmfs/volumes/datastore_name/offline-bundle.zip

Note: If this command fails, unzip the file and try running the same command. If hostd does not respond, try using localcli instead of esxcli.

For example:
localcli software vib install -d /vmfs/volumes/datastore_name/offline-bundle.zip
Restart the ESXi host.
To confirm that the VIB is installed successfully, run this command:

esxcli software vib list | grep -i vib_name
Exit maintenance mode.
