Yes if you bank with HSBC Singapore for example.
They look at it on a case by case basis. 500k in securities will not cut it I can tell you now. You must show you are able to sustain yourself and will never be a burden to the principality. You most important must show pre-arranged adequate accommodation. As you won't fall under Law 887 your money will be drained very quickly in Monaco on accommodation so check any cheap apartment you see online is not under Law 887 or 1291/1235.
I don't know your specific situation but you would need a Monaco bank reference to be successful. The authorities prefer if you provide a letter from a local bank in 2024 saying you have sufficient means to survive in Monaco as it makes the decision process easier from what I was told when I looked into it years ago. 500k in my opinion will not be enough to show you even have enough income from that to live on in Monaco in 2024. You will be at the back of the queue behind millionaires and billionaires.

P.S If you show you will be of economic value to the principality that is helps also during in person interview.
