The two processes don’t really conflict with each other. ondemand.service focuses on setting the CPU Frequency Scaling governor.:
$ systemctl status ondemand
● ondemand.service - LSB: Set the CPU Frequency Scaling governor to "ondemand"
Loaded: loaded (/etc/init.d/ondemand; bad; vendor preset: enabled)
Active: active (exited) since Thu 2019-10-31 05:30:09 MDT; 1 weeks 3 days ago

Tuned on the other hand focuses on optimizing performance of storage devices (including swap):
The Tuned Project
Tuned is a system tuning service for Linux. It:
- monitors connected devices using the udev device manager
- tunes system settings according to a selected profile
- supports various types of configuration like sysctl, sysfs, or kernel boot command line parameters, which are integrated in a plug-in architecture
- supports hot plugging of devices and can be controlled from the command line or through D-Bus, so it can be easily integrated into existing administering solutions: for example, with Cockpit
- can be run in no-daemon mode with limited functionality (for example, no support for D-Bus, udev, tuning of newly created processes, and so on) for systems with reduced resources
- stores all its configuration cleanly in one place – in the Tuned profile – instead of having configuration on multiple places and in custom scripts
There should be no problem keeping ondemand service running or disabling it before installing tuned.
