How can I minimise latency during gaming on PS5?

My son's PS5 is connected to one of the OPNsense firewall ports (LAN3), and I want to prioritise (or reserve) upload bandwidth for it in OPNsense. Basically, when he is gaming and I'm uploading large files, his latency jumps from about 20 ms to 150 ms. How can I stop that from happening?

I already read this article, is that the approach I should follow? Ideally, I'd want to assign to the PS5 5 Mb/s of bandwidth in upload when he is playing, but then when the PS5 is switched off, I'd want to be able to use the whole bandwidth for my devices.

I would say that what you want to achieve is more along the lines of this. What you want to aim for is latency, not bandwidth.

Okay, I'll try this evening, thanks.

P.S.
1. should I consider to shape the WAN upload only or also WAN download?

2. although the PS5 is on a different subnet, in the section 'source' of the rule the default value is "any" so that covers all the networks, right?

3. this setup covers everything leaving WAN, including VPN traffic which I have on another port (LAN2), and I suppose it's perfectly fine, no need to worry ?

1. no
2. yes
3. yes, no need to worry
