Stricter type checking for string command choices

Hi, was wondering if this is possible. In this example I am doing a command that can change my bot's status from Online to Invisible/Idle/Dnd. I want to ensure that the value choices in addChoices have the PresenceStatusData type in case the string values are changed in a future API.

import { ApplicationCommandRegistry, Command } from "@sapphire/framework";
import { ChatInputCommandInteraction, PresenceStatusData } from "discord.js";

// ...

public override registerApplicationCommands(registry: ApplicationCommandRegistry) {
  registry.registerChatInputCommand(builder =>
    builder
      .setName(this.name)
      .setDescription(this.description)
      .addStringOption(option =>
        option
          .setName("status")
          .setDescription("Online status")
          .setRequired(true)
          .addChoices( // possible to do stricter type checking for value?
             { name: "Online", value: "online" },
             { name: "Idle", value: "idle" },
             { name: "Do Not Disturb", value: "dnd" },
             { name: "Offline", value: "invisible" },
          )
      )
  );
}

import { ApplicationCommandRegistry, Command } from "@sapphire/framework";
import { ChatInputCommandInteraction, PresenceStatusData } from "discord.js";

// ...

public override registerApplicationCommands(registry: ApplicationCommandRegistry) {
  registry.registerChatInputCommand(builder =>
    builder
      .setName(this.name)
      .setDescription(this.description)
      .addStringOption(option =>
        option
          .setName("status")
          .setDescription("Online status")
          .setRequired(true)
          .addChoices( // possible to do stricter type checking for value?
             { name: "Online", value: "online" },
             { name: "Idle", value: "idle" },
             { name: "Do Not Disturb", value: "dnd" },
             { name: "Offline", value: "invisible" },
          )
      )
  );
}

Yeah I'd do the second. Just type cast it.
