Can I switch from monthly to a 1-year VPS plan?

Need a backup server for my website. I'm thinking about getting VPS-2 2027 (4 cores, 8 GB RAM).

My question is: can I order it with no commitment first, and if everything works well, after a month switch to a 1-year commitment? If yes, how does that work? I couldn't quickly find an answer in the documentation.
