In any definition worth its salt, bosons would be material.
We've been over this before quite thoroughly. You've never been able to coherently argue that bosons are objects with mass and volume or that bosons are the same as or indistinguishable from objects that have mass and volume.
You have also never been able to coherently argue that non-conserved quantities such as matter are somehow more "fundamental" than conserved quantities such as energy and momentum.
My claims are based on, or mere quotations of, facts and definitions, not on metaphysical allegiance, such as yours.
Matter:
(in physics) that which occupies space and possesses rest mass, especially as distinct from energy:
matter - definition of matter in English | Oxford Dictionaries
2 b : material substance that occupies space, has mass, and is composed predominantly of atoms consisting of protons, neutrons, and electrons, that constitutes the observable universe, and that is interconvertible with energy
Definition of MATTER
Matter can be identified by its characteristic inertial and gravitational mass and the space that it occupies.
Classification of Matter
There are many possible definitions for matter. In science, matter is the term for any type of material. Matter is anything that has mass and takes up space.
EXAMPLES OF MATTER
Proton
Atoms (e.g., a helium atom)
Molecules (e.g., water, sugar)
Compounds (e.g., table salt, silicon dioxide)
Cat
Tree
House
Computer
EXAMPLES THAT ARE NOT MATTER
Not everything we can perceive consists of matter. Examples of things that aren't matter include:
Photons (light)
What Is the Definition of Matter?
Matter is anything that has mass and occupies space.

All particles fall into one of two classes, bosons or fermions. Two bosons with identical properties can be in the same place at the same time, but two fermions cannot.
There are two kinds of elementary particles in the universe: bosons and fermions. Bosons don’t mind sitting on top of each other, sharing the same space. In principle, you could pile an infinite number of bosons into the tiniest bucket. Fermions, on the other hand, don’t share space: only a limited number of fermions would fit into the bucket.
Matter, as you might guess, is made of fermions, which stack to form three-dimensional structures. The force fields that bind fermions to each other are made of bosons. Bosons are the glue holding matter together.
