To prevent windows from changing system time just copy this to a blank notepad text file and save as a *.reg (e.g.; win11-utc.reg) file:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation]
"RealTimeIsUniversal"=dword:00000001
After that either double-click or right click and add this *.reg file to your registry. This will set the windows time to utilize RTC at UTC. This way you’ll not have to get into FW BIOS and keep flip-flopping the RTC time clock.
(setting this on standalone windows install is also good idea imo, I prefer to set reference clocks at UTC)

I also own a Framework 13 AMD laptop. I have ArchLinux, Fedora 39, Debian 12, and Windows 11 Pro installed on this.
I use rEFInd boot manager to select the OS to boot at boot time. I have disabled the os_prober in each of the GRUB, and run a systemd unit to rewrite the default boot manager to rEFind during boot.
My rEFInd systemd service file looks like this:
cat /etc/systemd/system/refind-make-default.service
## file: /etc/systemd/system/refind-make-default.service
[Unit]
Description=Make rEFInd the default EFI boot loader at startup/boot
## start after local-fs
Requires=local-fs.target
[Service]
ExecStart=/usr/sbin/refind-mkdefault
[Install]
WantedBy=multi-user.target
Then run the following command to enable this service to run at boot/startup:
sudo systemctl enable refind-make-default.service
This setup is similar to my old Dell Inspiron 7390 laptop - ArchLinux, Fedora 39, Ubuntu 23.10 and Windows 11 Pro. With this setup, I have never had Windows11 boot capture and replace my default rEFInd in the efi stub. If this happens then boot into the FW BIOS and set the boot order right in there OR use a linux live usb, boot into live and run efibootmgr.

The selection in rEFInd just chain loads the respective nix’s GRUB efi stub (or windows BOOT efi stub) and there on it continues to boot the selected kernel in that distro/OS.

Its pretty simple to install rEFInd if you have secure boot turned off. If you need secure boot then read the refind wiki/support documentation on how to utilize shim to sign refind binaries.
