New to IF, need to lose a little weight in a month, will it work?

I'm new to intermittent fasting. Although yeah, I have done it once, involuntarily because of my busy schedule, and I lost weight.

I'm around 6ft (1.8m), and weigh around 88-90kgs. 25, M.

So I have an important event coming up in exactly a month, for which I'd like to lose a bit of weight. I got a little belly fat as well. Can I lose like 4-5kg weight by doing IF, coupled with mild cardio (like brisk walking) for 2 hours (10km?) daily?

Thanks!
