R11e-LTE LTE upgrade ... over OVPN Tunnel ?

I have a RB4011 (home) and a LT-Ap (garage) connect through a OVPN Tunnel
can i perform the LTE Module upgrade “interface lte firmware-upgrade lte1 upgrade=yes” during the Tunnel (over LTE) is established ?
Or have i to go down to the garage (WLAN) ?
thx for info

Generally you need a connection to your device while the upgrade is in progress, but the upgrade breaks connection.
But this may help: unattended-lte-firmware-upgrade
Just copy’n’paste the code into your device’s terminal.

works like a charm !!!
thx Chris !!!
