   No. They get re-formatted to EXT4 during the imaging process.

   I have 3 Pi using 64Gb cards without a problem. The rest use 8 or 32GB   
   cards. I think they're currently all Sandisk although I have used some   
   others (Lidl , Fuji , Samsung)

   Cut from the ad --   
   ▲Fast Transfer Speed - The Micro SDXC card adopts Speed Class UHS-I(U1)   
   and Class 10(C10) and provides you with 80MB/s of read speed and 15MB/s   
   of write speed, and supports full HD video recording. (The Performance   
   may vary based on host device, interface, usage conditions, and other   
   factors.)

   I usually use SanDisk too but had run out of the 64Gb cards.   
   The 32Gb cards in use, in security cameras, are getting past 92% full on   
   one of the cameras, hence me wanting a larger card.

   It causes me a great deal of regret and remorse   
   that so many people are unable to understand what I write.
