Only to your wallet. For passive guitar controls, a
10 VDC cap would be fine.
First, some terminology definition is needed.
By "treble cut" (the removal of treble frequencies) do you actually mean a "treble preservation" circuit (also called a treble bleed) whereby the treble is preserved as the volume is turned down?
The proper terminology for this would be a treble bypass (it bypasses the increasing high-side resistance of the volume pot as it's turned down).
The generally proper value for a treble bypass circuit is a cap around 0.001 uF (1 nF) used in conjunction with a 100K to 200K resistor. Some prefer this in series with the cap and some prefer it in parallel.
This is implemented on a volume control, and is independent of a tone control.
Now, if you're asking for a 0.022 uF cap in conjunction with a fixed resistor for a two-stage implementation of what the high (treble) cut
tone control in a PRS does, this is fairly straightforward.
In summary; the volume pot would work just like a volume pot, but the DPDT push pull pot would switch between no high-cut tone control and a 0.022 uF cap in series with a determined fixed resistor for a preset high-cut tone function.
Is this correct?
Since the SE One has a pickguard mounted volume pot, any DPDT push pull pot should work.
You might be able to use a dual concentric pot to effect both the volume and tone controls in the same mounting hole.

Keep in mind, at aboot $400 AHTSBUTTB (after holding the salesman's breath until they turn blue), the PRS SE does not have "vintage value" and a second hole might be able to be drilled for a *tone pot depending on the cavity dimensions.
*Or a switch, or a roller skate key.
I've often espoused using the SE series as starting points for custom modifications as they are inexpensive good quality guitars.
FOR CONTROL THROUGH BODY SE's
I have both the solid body P-90 version (two pickups) and the semi-hollow P-90 version of the PRS SE series. The tops are about 0.200" (5mm) thick. This precludes the use of many pots as their threaded bushings are too short.
Also, both of mine seem to have oversize diameter shaft bushing mounting holes, so the pots wobble about until they are tightened in place. This might indicate that 3/8" bushings could be used.
I do have some push pull pots that have a 3/8" diameter 3/4" long threaded bushing that would work with thick top. StewMac sells one that has this bushing. The other units indicate that they have 3/8" long bushings, but with the lock washer there likely isn't enough length to work.

I checked the tone control mounting hole on the semi-hollow P-90 version of the PRS SE. It's about 8.9 mm in diameter (0.35") and the top is 5.4 mm (0.213) thick.
Fitting a pot with a 3/8" long bushing might be difficult. The PRS pots have a bushing length of about 10 mm (0.40"). They use a thin lock washer and a very thin surface washer with a fairly thin nut 1.27 mm (0.50").
The dual concentric pot's 3/8" long bushing is an issue, especially with the 0.062" lock washer and the 0.090" thick nut. If you look at the picture though, there are two folded down anti-rotation tabs on the pot (what the lock washer sort of does). One of these could be folded up at 90 degrees to the mounting surface, a blind hole drilled for it (one that DOES NOT go through the top of the guitar), and just the nut and a thin flat washer used to retain it.
Ergo, one could have concentric volume and tone controls.
