Liquid Volume Shader:
Are they available here in the store?
If so, can anybody share a link, please?

Well, there is a dispersive water shader in the Default Resources (for Iray). There are also several packs with liquids in the store. What exactly are you wanting?
The best: https://www.daz3d.com/sy-pool-waters-iray
other shapes: https://www.daz3d.com/sy-the-depths-iray, https://www.daz3d.com/sy-rippling-water-iray
Refraction index: 1.33
Thin walled: off
DAZ studio supports volume shader for a while and comes with a volume cloud shader. so I ask for a liquid volume shader.
The need for a liquid volume shader is moot, since you can use the refraction to make a hollow object look like it's filled with liquid with what already exists.
What do you want a volume water shader to do?
It depends on what you mean by a Shader.
Properly speaking, a Shader is a specific code setup to interact with Iray (or whatever). There's Iray Uber (with Specular and Metallicity options which are almost different shaders), PBRSkin, VDB, and a few weird smaller items (like some of my shaders).
Material presets are specific settings/parameters for those shaders, but a lot of people use the terms interchangably.
Iray Uber has good code to handle refractive substances, like glass or water, with SSS to expand that into various degrees of cloudiness.
If what you want is 'material presets for liquids', there's a bunch in the store.
If you actually mean a separately coded liquids shader, not so much, but I'd wonder (as Fishtales posted above) what exactly you would want it to do that Iray Uber cannot.
VDB shader needed to be coded specially because it does something radically different than the other shaders. Instead of having surfaces with interaction with light, it has voxelized stuff. A totally different approach.
DAZ studio supports volume shader for a while and comes with a volume cloud shader called "Simple OpenVDB MDL Volume" in /Shader Presets/Iray/DAZ Volume. So I ask for a liquid volume shader.

If people are asking you to clarify what you're looking for, just repeating the same thing isn't going to help.
The big question is: Why? Vdbs are for what is supposed to be tiny particles that get more obscure with depth. Mist, dust, etc. At least, that's my basic understanding. If you're wanting to simulate murky water, you can just as easily do so with a normal, hazy vdb with a solid water surface above it for the ray tracing. Do you have an image example of the effect you hope to make from it so we can better understand what you're trying to achieve?
The VDB is what provides the variance, not the sahder - so to do something similar with liquids you would need a suitable object from a liquid simulation, which as far as I know a VDB could already do (Fluidos uses VDBs as its working files).
