just install the new SSD and restore it with timemachine ?

Pretty much... yes.

I'm assuming here your Time Machine (TM) backup is to a local USB drive? Just install the new SSD then option key boot to the TM disk. That will get you to a recovery screen where you can use Disk Utility to format (erase) the new drive. Then quit Disk Util and click restore.

Hopefully, your air is running at least a High Sierra bootrom.

You can see the bootrom in system report.

If you installed Catalina to the Air with the original SSD inside, the MacBook will automatically update the bootrom.
