Trending @Infosys; Can I take 1 month leave at once?

I'm considering requesting a one-month leave for personal reasons, without specifying the government examination. I'm currently involved in a support project, and my team can manage my tasks during my absence. I'm unsure if project leads typically approve such leaves, or if I should consider stating a different reason. Additionally, I am not yet eligible for sabbatical leave as I haven't completed the required two years at Infosys. Any advice on how to approach this situation would be appreciated.
