Hi aspirant,

At first it is all ok if you are not prepared and do not want to appear for the examination but it's recorded to atleast appear in the same so that you can be aware of difficulty level and type of questions asked. Now to be eligible for jee main or advanced examination the basic criteria is that the candidate must have completed intermediate with PCM as subjects generally with 75 percentage aggregate. In addition, he or she can only appear for JEE main in consecutive 3 and JEE advanced in consecutive 2 years starting from the year of intermediate examination.

So you can directly appear in JEE main and advanced 2023 without appearing this year.

Hope it helps!
