Pausing on chian sales?

hello, is it possible to turn off the ability to sell the minted tokens?
this way i can mint and upload meta data to each token individually and after all is done i can turn on trading?

Do you mean pausing on secondary or pausing a claim page? It’s not possible to pause the transferability of tokens that are already minted, but you can pause minting by changing the end-date to be in the past.
