Hello,
Thanks for getting in touch with us.
Through our plugin, you cannot provide access to the shop manager to change our plugin settings.
For that, you have to use a third party plugin. Here we suggest one free plugin that you can use.
Advanced Access Manager:
https://ww.wp.xz.cn/plugins/advanced-access-manager/
This plugin will help you to sort out your issue, and by that Shop Manager user can edit our plugin settings.
Let us know if you have any other query.
Thank you,
Multidots
