is it possible to set vars in cmds?

I need a run a command before vars are defined, it this possible?

for example:

pkg-manager bump patch
VERSION=$(pkg-manager get current version)
git commit -m "bump: {{.VERSION}}"
git tag "v{{.VERSION}}" -m "v{{.VERSION}}"

pkg-manager bump patch
VERSION=$(pkg-manager get current version)
git commit -m "bump: {{.VERSION}}"
git tag "v{{.VERSION}}" -m "v{{.VERSION}}"
