This:

@bot.slash_command()
async def toggle_soundboard_perms_false(ctx: discord.ApplicationContext, channel: discord.VoiceChannel):
    await channel.edit(overwrites={ctx.guild.default_role: discord.PermissionOverwrite(use_soundboard=False)})
    await ctx.respond(f"Soundboard perms for {channel} have been toggled off.")


@bot.slash_command()
async def toggle_soundboard_perms_true(ctx: discord.ApplicationContext, channel: discord.VoiceChannel):
    await channel.edit(overwrites={ctx.guild.default_role: discord.PermissionOverwrite(use_soundboard=True)})

    await ctx.respond(f"Soundboard perms for {channel} have been toggled on.")

@bot.slash_command()
async def toggle_soundboard_perms_default(ctx: discord.ApplicationContext, channel: discord.VoiceChannel):
    await channel.edit(overwrites={ctx.guild.default_role: discord.PermissionOverwrite(use_soundboard=None)})

    await ctx.respond(f"Soundboard perms for {channel} have been reset to default.")
