I have obtained a Macbook Air which when it boots displays a white
screen with a grey circle and slash through it. From what I can find it
seems to be to do with version of OS needs updating. Anyways to solve
this I have found the "Option + Command + R" command to update it to the
latest version. Will this wipe the drive to do so as I want to keep all
the data on the drive.

Pressing Option + Command + r keys will start your Mac from macOS Recovery.
macOS Utilities window will open allowing you to install macOS without removing all data.

If you acquired a use/pre-owned laptop, then you should erase the whole drive and perform a clean install of macOS to remove all traces of the previous owner to ensure that no malware or other problems exist. Here is what the previous owner should have done before selling the laptop, however, I never trust other people so I would personally wipe it myself just to be safe.
Option Command R on MacBook Air. Will it wipe drive?
