"You can BYO when you DIY"

[Odessa Dawn]

An added joy of doing it yourself is that you’re not confined to camp between game drives – you can cruise all day, stopping to refuel at different rest camps as you go.
And, because you can BYO when you DIY, you don’t have to worry about taking out a loan every time you want a beer.

Does "You can BYO when you DIY" stand for/mean you can bring your own (goods) when you do-it-yourself?

Yes.

BYO generally refers to alcohol which makes sense because the piece goes on to say that you don't have to "take out a loan every time you want a beer".
In the UK at least, a bottle of wine in a restaurant will set you back approximately £15. At BYO restaurants, you can pop to the local supermarket or off licence and buy a bottle for under £5, take it to the restaurant with you and enjoy it with your meal, saving £10!
