Can I just upgrade the 1TB SATA HDD to a SSD with SATA adapter and conversion kit without replacing the NVME SSD blade or do I need to change both? Another scenario would be if possible could I replace the current 32gb NVME SSD blade with a 1TB one and get rid off the main SATA hard drive?

As you can quickly see the blade is hard to get to: iMac Intel 27" Retina 5K Display 2019 Blade SSD Replacement You will need the OWC thermal sensor (to prevent runaway fan noise) and the adhesive strip plus the cutting tool: https://eshop.macsales.com/item/OWC/DIYI… Here are the full kits available: https://eshop.macsales.com/upgrades/imac…
