Under the new laws in Malaysia’s Terengganu state, first-time offenders could be imprisoned for up to two years and fined

So can they leave Islam and not be bound by the obligation to show up?

Sounds like that's illegal too. Rather more illegal.

Attempted Apostasy and Apostasy offences in Malaysia

Terengganu
Criminal offense
Apostasy
Repentance in 3 days or death sentence and forfeiture of property.

Says that the federal government apparently has a constitutional issue with states imposing the death sentence, so it hasn't been applied, though.

In Malaysia it's illegal, but it has yet to have a death penalty for apostasy. Kelantan is currently trying their best to make it legal tho, so we'll see where that goes. The punishment is an expendable arrest where the syariah courts will send their officer to detain you for a year or two and sending you to a Muslim therapist or something. Yea they treat people who committed apostasy like they have some kind of mental problems. And how long they will be detained will depend on the syariah courts. If they think they should keep you in their "correction center" for 5 years, then you'll be there for 5 years. Which means, yes, you're most likely are gonna lose your job, house, and car just because you no longer believe in what they believe in.
