The 500Gb for R50 promotion has ended on 5th of May 2018. It is possible that as part of the Mo'nice promotion, you could be offered a 450Gb option, but it is not guaranteed and it might only be once off. Since the offers are customized, you never know until you check.
I have 2 pre-paid LTE SIM cards and neither of them have the 450Gb option. The one has a R5 for 5Gb option, but you can only buy it 2 times. So kind of useless. The other SIM has no night-time data option at all.

Yes I recall a post saying you can do this by changing the tariff on your contract sim (the person was helped at a Telkom store) .
You can also change the tariff plan on data bundles via *180# , or login & follow the prompts on Telkom’s portal :
....Before you go for it just double check your signal’s from a Telkom tower as night surfer data is only available on their network - won’t work on MTN roaming.
As @SynergyZAsays, the 500G night surfer offer ended 5 May - more info on this thread :
Hope this helps
