Yes:
udev on /dev type devtmpfs (rw,nosuid,noexec,relatime,size=8021332k,nr_inodes=2005333,mode=755,inode64)
but this is how udev mounts it by default. Now I did:
# mount /dev -o remount,exec
and I got
udev on /dev type devtmpfs (rw,nosuid,relatime,size=8021332k,nr_inodes=2005333,mode=755,inode64)
and now it fails differently:
