Hi @Sharmila Chinnasamy -- Welcome to the Atlassian Community!
What do you mean by "Scrum capacity planning"? For example is it one of these:
With out-of-the-box features, a team can do #1 using the velocity report to decide how to plan upcoming sprints.
There is nothing built-in to support approach #2, which is usually okay: teams can discuss at planning what is possible/likely based on current conditions, including who's available during the sprint.
