Can a high school graduate work in Malaysia?

Hi everyone, my boyfriend has received a job offer as an IT technician in Kuala Lumpur with a 3-year contract and a salary of RM15,000 per month. The issue is that he only graduated from high school and doesn’t have any formal course certifications or reference letters from previous employers, as he has only done freelance work. Is it possible for him to obtain a work visa? Thanks in advance!
