As state in magento documentation https://devdocs.magento.com/guides/v2.3/extension-dev-guide/declarative-schema/db-schema.html#disable-a-module modules disable will drop those modules' db tables, i.e. data will be lost. If you plan to restore it later don't forget to use –safe-mode=1 option of setup:upgrade command or create db dump.

1. Truncate these tables (or remove rows with udropship_vendor!=0): catalog_product_index_price, catalog_product_index_price_replica, cataloginventory_stock_status, cataloginventory_stock_status_replica

   truncate catalog_product_index_price; 
   truncate catalog_product_index_price_replica; 
   truncate cataloginventory_stock_status; 
   truncate cataloginventory_stock_status_replica;

2. Collect modules to disable using this command

   bin/magento module:status| grep Unirgy_

3. Disable unirgy modules using this command (replace <modules to uninstall> with actual module names returned by prev command)

   bin/magento module:disable --clear-static-content <modules to uninstall>

4. Run setup:upgrade command

   bin/magento setup:upgrade

5. Run module:uninstall command (replace <modules to uninstall> with actual module names returned in step 2 command)

   bin/magento module:uninstall --non-composer <modules to uninstall>

6. Run reindex commands

   bin/magento indexer:reset cataloginventory_stock catalog_product_price 
   bin/magento indexer:reindex cataloginventory_stock catalog_product_price
