 Better to maintain pre-configured spare SD cards...

 Maybe plug in a USBSD-card reader and use

Accessories/SD Copier

{I've not tried that -- I just keep a shell script of apt commands on my
Windows box, since it I prefer to rebuild full Raspbian /with updates/ from
the NOOBS full download and an on-line connection. Relying upon copies of
some downloaded .DEB files puts one at risk of having packages missing
security updates, et al -- which requires an on-line connection just to do
apt update/apt upgrade to correct them}
