As macOS Tahoe will be release on 15 September 2025, I installed on my Macs with the latest Sequoia the profile to defer Tahoe for 90 days:
Defer90.mobileconfig
	
	
	
		
along with a profile to prevent automatic download and installation of updates:
SoftwareUpdate.mobileconfig

As Apple has depreciated enforcedSoftwareUpdateMajorOSDeferredInstallDelay and SoftwareUpdate, it is unclear at the moment if the profiles will work and prevent Tahoe for being shown in Software Update on Macs running Sequoia.
