Best way to disable a specific plugin?

[GNOMES]

I have a few plugins that I keep configs around for testing/playing with in free time. Currently I am commenting out all the lines in their dedicated config files except the initial return and ending curly:

return {
-- commented out configs
}

While only a few milliseconds, I do see that these Lua files are sourced by Lazy when looking at profile.

Is there a more "Lazy" way to disable/ignore these?

Just add something like the below at the top?

if true then return {} end

{
    "plugin",
    enabled = false,
}

I think commenting out is best. Because when you look at the init.lua, it is easy to see if it is enabled or disabled by highlighting.

I append # to plugin_name.lua ,It become plugin_name.lua#.It can disable plugins

I created lazyflex.nvim. The plugin facilitates the enabling/disabling of multiple plugins using a few well-chosen keywords.
