From OS X 10.7 Lion (2011) onward, macOS is strictly 64‑bit.
So any version you want — Sierra, High Sierra, Mojave, Catalina, Big Sur, Monterey, Ventura, Sonoma, Sequoia — is already 64‑bit.
All macOS versions from 10.7 (Lion) onward are 64-bit only (with the exception of early 10.8–10.14 supporting some 32-bit apps). For Intel-based Macs and Apple Silicon (via Rosetta), the resulting ISO will be fully 64-bit compliant.
Open Terminal and run the following commands one by one.
First, create a blank disk image that will hold the installer:
hdiutil create -o /tmp/MacOSInstaller -size 14g -volname "Install macOS" -layout SPUD -fs HFS+J
