restrict purchasing Userpoints with Userpoints

-- HikaShop version -- : 2.3.3

***GOAL : I do not want users to purchase userpoints with userpoints.

If I could assign different payment method to different categories, this could be solved.
But I have tried the "restricting to shipping method" way to do it, like others pointed out, even after restricted to shipping methods accordingly to warehouses, all payment methods are still shown on the check out page.

Restricted by currency could be another direction to resolve this problem, because I created a currency of userpoints, however, Hikashop simply auto-converts the currencies...as shown in the attached image.

Can anyone help resolve this?
Thank you very much!

Hello,
Note that the solution can be to restrict your product categories to different shipping methods (using warheouses) and then you'll just have to restrict your payment method to your shipping method through the "shipping method" option of your Payment method configuration page.

yes, that is what I did, but by doing that, all payment methods are still shown on the check out page

is there any other way to do it?

Are they shown when your shipping method isn't available for your order ?

yes,

I will really appreciate it. I need to resolve this problem
Thanks

Can you show me some screenshots of how you configured your payment method ?

I posted this before, was asked to start a new topic

Hello,
I just tested it on my end and it worked fine, can you give me a temporary access to you backend through a private message so that I can directly test it and find from where your issue is coming from ?
Thanks.
