There's no graphical installer officially, no. There are many Arch derivatives with installers though, like CachyOS.
Installing Arch is literally running like 10 commands, and it's all very well documented.
- Put your Archiso USB stick in and reboot
- Format your disks if needed, mkfs
- Mount root and boot partitions
- Run pacstrap to install base system
- Generate fstab
- In chroot, set time and locale(s), set password, install bootloader
- Choose/install a network manager, like systemd-networkd
- Reboot
Now you're running Arch. Make a user and install a DE, optionally.
