Creating a new quote record for each of the different product configurations and syncing the most likely to be purchased back to the opportunity will ensure that their quotes and opportunities reflect their sales.

Syncing a quote with an opportunity will update the opportunity amount, stage, and expected revenue fields based on the quote information. References: https://help.salesforce.com/s/articleView?id=sf.
