this is covered in my fork grawcho
there are a few more options there to "tfx build queue" like adding queue parameters, queuing with brach / commit id, changing priority, adding demands, queuing synchronously (wait), and more.
here is the help text as reference (i'll update the docs in a few days)
Command: queue
Queue a build.

Arguments:
--project, -p Project name.
--definition-id Identifies a build definition.
--definition-name Name of a Build Definition.
--parameters Build process Parameters JSON file / string.
--priority Queue a build with priority 1 [High] - 5 [Low] default = 3 [Normal]).
--version the source version for the queued build.
--shelveset the shelveset to queue in the build.
--demands Demands string [semi-colon separator] for Queued Build [key / key -equals value].
