Help modifying a script- vgpu bypass

Dev Zone Code
1

I’m not fond of my driver reseting at 3am because sometimes I’m using it then

I’d like to modify this script but I have VERY limited coding knowlege
the script is from

I believe I want to modify the
Set-vGPUEternalTrial.ps1

what I would like to do primarily is change the time from 3am local to 6 am
optionally Id like to change the the period from 1440 minutes 0x5a0 to 4095 minutes ( using a converter I THINK this value is 0xFFF) and change the driver reset to every other day or longer if I can use more than 3 digits of hex code like FFFF

I assume these I can just modify from

@{
Name = ‘UnlicensedUnrestrictedStateTimeout’
PropertyType = ‘DWORD’
Value = 0x5a0
}
@{
Name = ‘UnlicensedRestricted1StateTimeout’
PropertyType = ‘DWORD’
Value = 0x5a0
}
@{
Name = ‘UnlicensedRestricted2StateTimeout’
PropertyType = ‘DWORD’
Value = 0x5a0
}

to

@{
Name = ‘UnlicensedUnrestrictedStateTimeout’
PropertyType = ‘DWORD’
Value = 0xfff
}
@{
Name = ‘UnlicensedRestricted1StateTimeout’
PropertyType = ‘DWORD’
Value = 0xfff
}
@{
Name = ‘UnlicensedRestricted2StateTimeout’
PropertyType = ‘DWORD’
Value = 0xfff
}

and change this from

$RestartTime = ‘3AM’,

to

$RestartTime = ‘6AM’,

right

That is correct above

But you should figure out what each unrestricted toggle does does
