Can I install new parts in store?

Hey peeps, Im fresh out of Highschool and im going to microcenter for the first time tomorrow, and I plan on bringing my whole tower with me since it basically is a day trip to go there. Anyways Im just curious if im able to bring my pc in and install the new parts there since im upgrading from ddr4 to ddr5. I need to basically put a new everything into the computer, and would appreciate if someone who knows computers more then I do can either stop me from destroying somthing or can put it together infront of me. Would save alot of stress to be able to test that everything works in store too.
