So, if you can, maybe applying at another consulate/embassy where they don't ask that could be better. Otherwise, book a fully refundable hotel stay(s) then.
Applying in Malaysia? Aren't you? So far, that I know, Malaysia is the sole country where they ask for that requirement, which if you ask me, is utterly nonsensical. Why? I'm a digital nomad, so I'm not living more than 1 maybe 2 months in the same place. I like moving and exploring new places. Said so, I wasn't asked for such a kind of lease when I applied for my DTV.
it totally depends on each embassy. Seoul and Tokyo were notorious for only allowing citizens and residents to apply, whereas in South East Asia and Taiwan anybody, including tourists, are more than welcomed to apply.
