Upgrade to Ubuntu 22.04 on Dell XPS 13 9310

I have Ubuntu 20.04 pre-installed on my Dell XPS 13 laptop. 
   I would like to know if an upgrade to Ubuntu 22.04 is possible now. 
  This latest version is LTS, so it is supposed to be accepted by Dell. 
     I would also like to know what is the best way to do it.
