What investigation could I do from this point?
If these are being caused by the game engine itself, there's pretty much nothing you can do. In the case of Valorant (or any online game), some spikes at this severity could simply be caused by random network access, also something you can't do much about.
If they aren't (something you would have to determine first; good luck), to start, you'd have use tools like LatencyMon to monitor your system processes while playing the game to see if there are any problem drivers or process causing or exacerbating these spikes. Irony is, running LatencyMon in the background can actually sometimes cause more spikes, and thus false positives (same goes for RTSS/Afterburner polling time FYI; keep it at or near default, or it can cause more frametime spikes as well).

Sure there isnt anything I could do to eliminate these stutters?
Reduce them in some instances for some games? Maybe. Eliminate them in all instances? No.

Maybe even upgrade hardware or invest in a 240hz Monitor ?
Better hardware will only reduce (not eliminate) these instances if it's the very thing causing them in the first place. If it's the given game causing them, then, no.
As for a higher refresh rate display, that would not fix this; the spikes originate on the system-side, not the display-side. For instance, a 63ms frametime spike at 237 FPS (240Hz) would simply occur over a 15 frame period (4.2ms x 15 = 63) instead of a 9 frame period (7.1ms x 9 = 63.9), and would look the same as it does on a 144Hz monitor.
