How to insert opportunity splits based on amount

Question

I want to insert opportunity splits based on below values:

Opportunity id
user 1,  amount - x
user 2,  amount - y
user 3,  amount - z

Looking at the fields of opportunity splits, we have field SplitAmount.

I am trying to execute following snippet in execute anonymous as below:

list< Opportunity > opp =  new list< Opportunity >();  
opp = [SELECT Id,Oppty_Supported_By__c,OwnerId, Renewal_ACV__c, Upsell_ACV__c FROM Opportunity];  
for(Opportunity o: opp)    
{  
OpportunitySplit ost = new OpportunitySplit();  
ost.OpportunityId=o.id;  
ost.SplitOwnerId=o.ownerid;  
ost.SplitAmount=o.Upsell_ACV__c;  

opp.add(ost);  

OpportunitySplit ost1 = new OpportunitySplit();  
ost1.OpportunityId=o.id;  
ost1.SplitOwnerId=o.Oppty_Supported_By__c;  
ost1.SplitAmount=o.Renewal_ACV__c;  
opp.add(ost1);  
}  

upsert opp;  

but getting the error as:

COMPILE ERROR: Field is not writeable: OpportunitySplit.SplitAmount

Is there any workaround?

Checked the Documentation shared by @crop1645. As the field property says updateable: false. Hence the answer is no and it is not possible.
