Can a high school graduate work in Malaysia?

Hello everyone! My boyfriend has received a job offer to work as an IT Technician in Kuala Lumpur, with a 3-year contract and a salary of RM15,000 per month. However, he only has a high school diploma and lacks any formal course certifications or reference letters from previous employers, as he has primarily done freelance work. Is it possible for him to obtain a working visa under these circumstances? Thank you in advance!
