Suppress `Alias` in help text option description?

The program below prints help text that gives the user alias help text in two locations:

import { initTRPC } from "@trpc/server";
import { createCli } from "trpc-cli";
import { z } from "zod";

const t = initTRPC.create();

const router = t.router({
  add: t.procedure
    .meta({})
    .input(
      z.object({
        left: z.number().meta({ alias: "l", description: "Left number" }),
        right: z.number().meta({ alias: "r", description: "Right number" }),
      })
    )
    .query(({ input }) => input.left + input.right),
});

createCli({ router }).run();

The help text:

Usage: index add [options]

Options:
  -l, --left <number>   Left number; Alias: l
  -r, --right <number>  Right number; Alias: r
  -h, --help            display help for command

Is there a way to hide/not print the Alias: l and Alias: r. They're redundant, given that -l, --left/-r, --right is printed at the start of the line.

Start at the createCli({ router }).run() entry point and trace how the schema metadata is rendered in command help. Compare the generated option description with the reported output and determine whether the redundant alias text can be suppressed. Done means help shows -l, --left and -r, --right with their descriptions but without the appended Alias text.
