Can The RISC-V Instruction Set Manual Volume I: Unprivileged ISA be viewed as one single specification?

Is this what you're looking for? https://github.com/riscv/riscv-isa-manual/releases/download/riscv-isa-release-056b6ff-2023-10-02/unpriv-isa-asciidoc.pdf

Thanks a lot! But what I want to know is that if this volume book can be seen as one single RV specification? Or it just a compilation of RV specifications? What's the definition of a RV specification?

Currently there is not one document that contains ALL ratified extensions. There are the Unpriv and Priv documents, various not-yet-integrated ISA extension specs, and various Non-ISA extension specs. On the ISA side the near-term goal is to integrate all ISA specs into two (Unpriv and Priv) spec documents. Regarding definition of a spec, each architecture extension (whether ISA or Non-ISA) has a specification. I would distinguish that from integrating ISA specs together into ISA spec *documents*. Although many people will loosely refer to the Priv document, for example, as the "Priv spec" insofar as it contains Privileged Architecture specs. Greg Greg
