In 2019 and beyond the storage capacity of SD cards has grown to 128gb or even 256gb. So some users have started using SD cards only since WiiFlow is capable of playing games from SD. But they noticed even without a USB HDD connected WiiFlow took a long time to boot up because it would still need to check for a USB HDD which also gave the device time to spin up. To bypass this the SD_only setting was added. On very first boot there will still be the long wait but then any boot after that it will boot much faster.
If for any reason you need to change this setting go to main settings>startup settings
