How to customize a public pool with Umbrelos using BTC Knox?

I’m currently using solomine on my node using BTC Knox with Umbrelos and experimenting with Public Pool.io. I would like to customize some settings, such as:

Coinbase Tag: I want to set a custom coinbase tag for my mining rewards.

Work/Job Update Time: I’d like to adjust how frequently the pool updates work/jobs.

Other Customization: Are there additional settings I can tweak to optimize my setup?

With Datum I found it relatively easy to make these changes, but using Datum for solo mining on a node is not entirely comfortable. Public Pool.io appears to suit my needs better, but I don’t know where or how to create these customizations.

Here’s what I’ve tried so far:

Looked through the Public Pool.io documentation but couldn’t find specific instructions for these settings.

Explored the BTC Knox interface on UmbrelOS but didn’t see obvious options for these customization.

Can someone guide me on how to adjust these settings in public Pool.io? Is there a configuration file or a specific command I need to use? Tips and examples are welcome!

thank you!
