RM is not supported in GOG, at least at the moment.
Currently pre order price for CP 2077 on GOG is USD 51.99.
Currency conversion rate is applicable.
You can consider buying physical copy from local retailer.
One of the local retailer is selling PC physical copy for RM 229.
Anyways, for PC physical copy, no DVD is provided, only a digital code (activate on GOG.com, DRM free) + physical contents as advertised in CP 2077 website.
Buying PC physical copy = 100% money goes to CDPR.
I do have some older generation games in my GOG library, so far didn't encounter any technical issue by running games on GOG platform.
