Is there a way to change the appearance of the reference number using BibLatex with a specific style?

I am using the phys style and would like to have the reference numbers appear in square brackets rather than as superscripts. Here is a MWE of what I have at the moment

\usepackage[giveninits=true,isbn=false,url=false,doi=false,hyperref=true,backend=biber, style=phys]{biblatex}

Test \cite{PhysRevLett.128.051103}

with sample.bib containing

  title = {Bondi-Metzner-Sachs Group in Five Spacetime Dimensions},
  author = {Fuentealba, Oscar and Henneaux, Marc and Matulich, Javier and Troessaert, C\'edric},
  journal = {Phys. Rev. Lett.},
  volume = {128},
  issue = {5},
  pages = {051103},
  numpages = {5},
  year = {2022},
  month = {Feb},
  publisher = {American Physical Society},
  doi = {10.1103/PhysRevLett.128.051103},
  url = {https://link.aps.org/doi/10.1103/PhysRevLett.128.051103}

This produces the output:

enter image description here

which, apart from the superscript reference number, is the style I wish to achieve including the hyperlink on the journal, issue, pages and year.

biblatex-phys has an option called biblabel with which you can switch between superscript numbers (the default biblabel=superscript,) or bracketed numbers (biblabel=brackets,) in the bibliography.




Test \cite{sigfridsson}

Bracketed number in the bibliography.
